I don't see the significance of this observation for the issue at
hand.  Eshell is an implementation of a shell in Emacs Lisp, and as
such, Emacs is part of it.  Therefore, we should compare what Eshell'=
s
command do with what shells+emulators do.

Eshell should have commands named like corresponding shell commands.
Having commands with no namesakes in popular shells makes very little
sense to me.
