tools/perf/ inherited the command-list.txt code from the Git project:

  git://git.kernel.org/pub/scm/git/git.git

in Git talk, 'porcelain' is the pretty stuff humans use. 'plumbing' is 
the lowlevel stuff humans dont get to see.

'mainporcelain' are the major commands you get listed when you type 
'perf' (or 'git').

( i've Cc:-ed the Git list as i never saw any real formal definition for
  this anywhere, maybe i got this wrong :-)

yeah, i'd suggest to do that - that will make 'perf bench' show up in 
'perf' output.
