It is somewhat an oxymoron that "*only* show X" can be combined with
"*only* show Y" in the first place.

For a reader to accept it without finding it awkward, the reader
must understand that

 (1) the command shows by default everything, but

 (2) if any of these "only show" options are given, the command
     stops showing everything and the user can pick which subset of
     "only show" options to give, which work additively.

But if the reader knows that much already, it is redundant to say
"can be combined with", isn't it?

So, I dunno.
