I agree.

For diagnostics for issues which (a) probably do not indicate mistakes
on the part of the programmer, and (b) can be readily ignored by the
compiler, the idiomatic handling is:

  if (pedantic)
    pedwarn (...);

Thus, only users who want pedantic error messages see the message.  They
can control whether the message is an error or a warning via
-pedantic-errors (or the C++ front-end's -fpermissive).
