Yes. That is ***a*** GRASS package that is installed on a particular
system. There is no sense in which that is ***the*** GRASS package that
"they" get whenever "they" install GRASS.

There's nobody but you designing this proposed enhancement. If you don't
know, then nobody does. When your design is complete, maybe you can find
some people to help you code it.

In any shop I run, that will absolutely be the first thing any new user
does who comes online with the platform.

That's hard to say. How many programs besides the ones shipped with the
Linux kernel call fork()?

There are a number of systems that have been made to interoperate with
GRASS. CD-ROM's have been produced and sold which contain mountable GRASS
locations.

In any event, even just the internal compatibility issues (current users'
scripts that would break when they upgraded to the nomenclaturally
beautified version) are sufficient to warrant severe caution when renaming
any interface symbols.

That tells me that there are people not currently using GRASS. I already
knew that, and that was not my question.

My question was why you think GRASS requires more users than it already has.
