We should move only the functions we think are most useful to
"standard Emacs Lisp".  The rest of the Common Lisp (emulation)
functions should remain in a separate library that is not loaded
by default.

But their functions etc. that correspond to Common Lisp functions
etc. should be renamed to drop the prefix `cl-', unless doing so
would conflict with existing Emacs-Lisp functions etc. that act
differently.

IOW, even when a Common Lisp emulation function is in a separate
library that is not loaded by default, we should drop its prefix
`cl-' unless doing so is problematic.
