The same way as we can "downgrade" studs to "fast-draw" variants,
I think we should be able to "upgrade" studs to be "logoed".

Locally I've replaced my stud.dat by this file,
but maybe in future tools like LDView could officially support
substituting studs by this "logoed" variant.

When a user turns on/off this substitution, this could
also trigger the corresponding LEGO logo switches in LDView's
POVRay export etc.

The previous implementation of this file referenced stud.dat and added the logo. This can lead to this substitution recursion:

1) software substitutes stud.dat by logoed stud-logo.dat
2) stud-logo.dat references stud.dat
3) software substitutes stud.dat by logoed stud-logo.dat
4) stud-logo.dat references stud.dat
5) software substitutes stud.dat by logoed stud-logo.dat
6) stud-logo.dat references stud.dat
...

this can simply be avoided by repeating the few lines here
which make up stud.dat
that's not as beautiful as referencing stud.dat from here,
but as it's just a handful of lines I find that tolerable

I agree it would be nice to have these officially, just hope that there is a chance to get some software support!!!

I think adding that should not be too difficult,
as many programs already allow to choose different stud
implementation mechanisms (MLCad, LDView do).

Using this file is just adding another option to those mechanisms,
my hope is that it'll be offered

As suggested at http://forums.ldraw.org/read.php?19,3095,3146#msg-3146, I think this could be achieved by putting the LOGO versions as their exsiting filenames in p/48/, and tweaking LDView to doing primitive substitution for stud* primitives.

that's tweaking to achieve substitution with existing tools.
instead, I think this file is directed more towards the future.
future versions of MLCad and LDView could simply use
it when their user asks them to substitute it for stud.dat,
the same way as today they can substitute stud.dat by stu2.dat
I would like to avoid tweaking

I wonder would it make any sense to have some meta-commands to establish relations between the normal and logoed studs.

With this I mean keep this file as it is and add something like this to stud.dat:
0 !SIBLING LOGOED_STUD stud-logo.dat

which would tell programs that the logoed counterpart of stud.dat is stud-logo.dat. This sort of syntax could open up other possibilities for other possible future relationships.

With "other possible future relationships" I mean, for instance, hollowed underside studs for the modern 1 x N plates.

I would like to suggest to include these logo primitives

in the next parts release, please.

may I humbly ask for cert votes here
so that we can finally get these logo stud variants
out with the next release?
otherwise they will sit another year here again...

I don't mind studs with logo. I too use them in my library.
But I think we should first agree on which logo that should be used,
(Why five different versions?) and where to put it in the library.
Normal (p) or High (p/48) resolution? A complete new section for hi-res parts?

I would suggest to keep it as simple as possible here.

IMHO, we should release these files
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/stud-logo.dat
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/stud-logo2.dat
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/stud-logo3.dat
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/stud-logo4.dat
http://www.ldraw.org/cgi-bin/ptdetail.cgi?f=p/stud-logo5.dat

Rendering software then can let the user choose which replacement
of stud.dat it shall apply. Options are:
- stud-logo
- stud-logo2
- stud-logo3
- stud-logo4
- stud-logo5
- stud-high-contrast

The latter is intended to be able to create high-contrast studs
as can be seen at the bottom picture of
