So it's just an optimization, intended to shorten the time to compile
Emacs and to reduce the installation size as well.  Note that apparently
loading a .elc file can be slightly faster than loading an "otherwise
identical" .el file presumably because it doesn't go through
load-with-code-conversion.

100% agreement.  But if someone wants to remove the no-byte-compile from
some of those files, I'm not necessarily opposed to it.
