No, no.  The *kernel* would do the recognition, not the documents.  It
would have a list of "acceptable" values for that macro.

Thus, "latex" would refuse to use any modules that didn't identify
themselves as Standard LaTeX, while "debtex" would accept modules that
identified themselves as "debTeX" or Standard LaTeX.

A particular API may or may not work at any time due to other factors,
but there's no reason why debTeX couldn't process any Standard LaTeX
document, or why LaTeX couldn't process debTeX documents.

Why not?  Why does embedding the name in a registration call offend you?

Give me some reasons.  "I don't like it" is really hard to argue with,
address, or even evaluate.
