The preference "perms=0" means that permissions should not be
propagated.  But Unison still sets the permissions of an updated file
based on the permissions of the previous version of the file, in order
to preserve file permissions.

You now need to add "dontchmod=true" to your profile as well, if you
don't want Unison to use chmod at all.
