Sounds like we're miscommunicating.  You're now talking about
`dired-on-marked-files', by which I guess you mean Phil's
`dired-on-marked-files-in-all-buffers'.  That doesn't require
any marking of subdirs.

But you didn't reply "It would be too tedious to mark subdirs",
to anything about `dired-on-marked-files-in-all-buffers'.  You
replied that to my mention of the Dired+ feature of selectively
acting on marked files & dirs in Dired buffers for marked subdirs.

And you seemed to be saying that for that the most common case
is to want to act on all marked lines in all Dired buffers for
subdir listings (at all levels).  IOW, no selectivity.
