It's been written last august, but in a branch that was rebased into
master around 3.1.4.15, so not all is lost. The only user so far is
Dave Cooper, and he's watching the list, so we can safely change the
API. The deeper question is: what exactly is the API we want?

Now that I look at the code, I believe one reason that
register-immutable-system works the way it does is so as to still work
after all systems are cleared, e.g. by a non-backward-compatible asdf
upgrade. See the (register-hook-function '*post-upgrade-cleanup-hook*
'clear-defined-systems nil) form in asdf/find-system.
