That is a phantasy argument, and you know it.

But this is a completely irrevant side discussion.

It is not the case that emacs has the goal to force users
to only write syntactically correct programs -
and, as said, there is no guarantee at all that a file
with a name ending in .c is in fact a C99 program.

In fact there is no guarantee that it is a C program at all.
For example, I have old files where the .c extension means
that it was compressed using the "compact" utility.
