Maybe I'm just paranoid, but I'm afraid that might turn out to be 
Using existing babl is out of the question because it is just way too slow.
Leaves improving babl, which I will be glad to do (or attempt) next. I 
just don't expect that to be a quickie. Some questions already came up 
and I'm sure there will be more. The algorithms will probably have to be 
twiddled with, maybe just a few more bits precision, maybe some floating 
point/integer/LUT combination -- I just don't know yet.
Once that's done, all current Lab conversions in GIMP can easily be 
ported to babl.
If it turns out I'm wrong and it's much easier and quicker than I 
anticipate -- fantastic. Throw those conversion right back out and it's 
babl all the way.
If I'm not, then it's a feature that could have been.



PS: As David already noted, the last patch doesn't have the conversions 
in libgimpcolor anymore -- so no additional API.
