This sounds like a good idea to me.

However, the question about introducing AM_FC_SRCEXT was rather meant
the other way round: Can there be uses where you would like to know for
some reason the answer to
  AC_FC_SRCEXT([f])

but in your source tree, you have files with extension .f that should be
compiled with $(F77) instead of $(FC)?  Then, decoupling the override
from the Autoconf macro would seem like a better choice to me, even if
it means that current packages would need to change AC_FC_SRCEXT ->
AM_FC_SRCEXT.  They need to adjust anyway, so I don't think that would
be a big issue.

Was this understandable?

I'll work on an updated patch.

Cheers,
Ralf
