It's a valid question, but it opens a can of
worms.  There's no consistency already. ;-)

Consider option `dired-garbage-files-regexp',
for example.

Generally, an option whose value is a regexp
is better named with `regexp' in the name.

`dired-omit-files' would be better named
`dired-omit-files-regexp' or similar.

FWIW, Dired+ has these additional options:

diredp-visit-ignore-regexps
diredp-omit-files-font-lock-regexp

And of course diredp-omit-lines-regexp.

If you really want to aim for consistency
then consider renaming `dired-omit-files'
to `dired-omit-files-regexp'. ;-)
