Hopefully LED lighting, which is much simpler, will also become much better and cheaper, and CFLs will become obsolete faster than incandescents...

Regrettably, things aren't as straightforward/easy as you think.
Yes, it is indeed true that for AC120V/240V based CFL requires rectification (to convert it into DC first) before it can be further fed into the circuity to work its magic.
Unfortunately, the circuitry does not/cannot take pure AC to do it's job RE: high frequency switching.
