I don't think of any new meta-commands as polution. Possibly over-population?
I've got mixed feelings about the LTrax solution.
It is very hard to know which meta-commands will be usable across many
applications. Certainly the original LDraw meta-commands are usable across
many LDraw compatible tools, but LPub supports any of the MLCad defined
meta-commands that are meaningful.
I created the SYNTH meta-command for flexible-part synthesis. I intentionally
didn't name the meta-command LSYNTH, because I wasn't sure what the actual
application name was going to be. Besides someone might come in and displace
LSynth with a better synthesizer. SYNTH seemed to reflect the intent of the
meta-command without it being bound to a specific application.
It is hard to know what the right philosophy is here. MLCAD has gone both ways
on this one.
