I agree that GPL might not be the right license to use here - I was just
using it as an example of how the "extension" problem might be dealt
with, as far as the license goes. Of course that we would always want
the LDraw format to be the most advanced, most useful format there is.
But that doesn't mean we shouldn't put something in the license that
might help achieve that goal.

The format with the most data. Example:
You take all the ldraw parts, and release them in a close format of your
own. This format also supports connection types, and all the parts you
released now have that additional data included in them.
The LSC sees this, creates a way to embed the connection info in the DAT
format - but the whole library doesn't include all that info yet,
because each part has to be reviewed, resubmitted, etc, by the
community.
Do you really think software won't start supporting the commercial
format, since it allows them to include the new features? I'm not so
sure.

You can't force the LSC to innovate in ways no one has ever thought of.
The LSC is only 5 people (I think?), and there is just no way to force
all the new great ideas to come only to those 5 people. If a commercial
entity came up with something neat, the LDraw library would have to play
catch up - and that might take a while. In that time, any new software
written would have a pretty big incentive to support the commercial
format, in addition to LDraw's.
Repeat this cycle a few times, and the LDraw format might eventually be
abandoned, as just too primitive to support. Maybe as an "import only"
mode, but not as a working format.
Does that make more sense?
