Still don't get it.  You're either requiring modified work to follow a
specific API, which is IMO non-free, or you don't get the desired
protection against impostors, as a modified work could simply return the 
latex identifier.

For the same reason that limiting the API of any program would be 
non-free.  I also wouldn't accept a C library that disallowed calling a 
modified function "printf".

Because freedom to change (or not change) the API is part of the freedom 
that I believe Debian guarantees to it's users.
