No offence meant; Emacs is older than many people on this list
(including me), both the language and the libraries did evolve quite a
bit, and then there is the problem of manpower - no surprise some code
in Emacs is rather dated.

Maybe - I just wrote about something I noticed, I don't read Emacs
sources on a daily basis (and I'm not competent enough in Elisp to
notice many things).

I have Emacs 24.3, maybe that's the reason.
