Because u-law and a-law are non-linear algorithms and the mathematics of FLAC (and AFAIK all lossless encoders) are build for linear PCM. Adding these formats would change the FLAC format altogether, decoders are not made to work with it (they can only output plain PCM) Best option would be converting these files to 16-bit plain WAV and compressing, but I guess files won't be much smaller that way. IMO best is to keep them as they are.
