The idea isn't necessarily to come up with new or alternative algorithms but
to codify current practice, where it makes sense.  So if 99% of the
implementations out there do, say, AES + x + y, then make the profile "AES + x
+ y", so that implementing just that one option is all that's required to give
you 99% coverage.
