But it doesn't hurt us to use the SPL autoload registry but it might
make some folks happy.

I didn't say you cannot do it. It's more or less a grep for "^class
([a-zA-Z0-9_]+) {"  on all .php files.

The only caveat is that t3lib and typo3/classes don't live in the ext.
directories and must be handled in an extra run. And don't forget that
it is for some reason possible to define the location of tslib via
constants (start of index_ts.php), but I don't mind if that feature goes
away.
