AFAIR, yes.  The command is intended to help users to clean up the eln-cache
of files _they_ compile, but it isn't supposed to touch *.eln files
installed as part of Emacs.  That's for sysadmins.  And besides, on many
systems the preloaded *.eln files are not writable by "normal" users.

See bug#48108, where this was discussed.
