This is a fair suggestion as the path component length is
generally too restrictive these days.
For example the coreutils sources don't comply with
the POSIX 14 char limit.

I suppose we could have --posix=all,naming,length
with -p equivalent to --posix=all

For my reference I wrote a similar util a long time ago
to split the checks over 4 levels of sensitivity,
when length and character patterns varying for each level:
