Hello.

Yes.

I don't have a plan to implement conventional regular expressions.
There are many variants for regular expressions (e.g. shell, perl, sed) and
users likely use characters with special meaning without knowing.
TOMOYO treats a character as literal unless prefixed by '\' character so that
users who didn't know the meaning of a character don't get unwanted results.

You will be able to use

  path_group ALL_INIT /bin/init
  path_group ALL_INIT /sbin/init

    +

  allow_execute @ALL_INIT

in the future (hopefully in Linux 2.6.34).
