Yes, in the same sense as -mint8 produces smaller code when applied.
Except, -mno-mainframe causes way less portability issues.

Marek's suggestion to use __C_task has some merit as well (and is IMHO
also compatible with other compilers, at least with IAR), but would
even require code changes.  Perhaps we could combine them: allow for
the __C_task attribute, and provide a command-line option that would
treat each implementation of function main() as if __C_task were
applied (so no code changes are needed).

Right now, we are already incompatible (with no option to the users to
get rid of the incompatibility), and surprisingly few users really
noticed it.

Both are valid goals.  We also need to be allowed to fix old mistakes.
See above: other compilers also require you to specifically request
that code-saving features.
