It would be nice if there was a way from scripts with a command line option
to ask hierarchy mode to only show a subset of the tree (e.g. with some
kind of pattern)

Then options like --pid could be obsoleted, but it would be far more
flexible and scale for all the sort keys which are supported, without
adding a lot of new command line options.
