I think this is too weak.

find -perm +symbolic_mode stopped being very useful with findutils
4.2.25 because it conflicted with POSIX.

The big change in 4.5 is dropping support for -perm +numeric_mode,
which might or might not be invalid syntax in POSIX, but does not
conflict with POSIX. It does conflict with chmod's intepretation of
+numeric_mode, which afaict from https://savannah.gnu.org/bugs/?38474
seems to have been the real reason for dropping findutils' support.

- find -perm +numeric_mode is not supported anymore. This syntax is
  unspecified/unsupported by POSIX. The functionality continues to be
  available with -perm /numeric_mode. (#38474)
