    Would it be possible to use compiler macros so that existing programs
    could continue to use these functions' un-prefixed names at compile
    time?

That would be possible, but it seems like a bad idea -- it would
confuse people reading the program.  Writing the calls with `cl-'
would be a clearer practice.

    That would be helpful but it would still prevent many programs from
    being contributed.

"Prevent" is too strong a word.  These programs would need some change
in order to be installed in Emacs.

Adding `cl-' in front of certain function names is a pretty easy
change to make; we could add a command like query-replace to do it
semiautomatically.
