The biggest problem with most of the alternatives to "CFC solvents" is
that they tend to be FLAMABLE! This produces significant problems in storage
and use that "CFC solvents" don't have.

Just imagine having a rework person scrubing a board with an Alcohol, 
Acetone, or Hydrocarbon based solvent... vapors drift down the bench and
find an ignition source..... .... ... .. .

I am sure suitable substitutes will be found... but they will probably
be more expensive (at least at first) and will undoubtedly have their
own unique problems.

P.S. I have heard that some companies have started introducing "environmental"
blends of different "CFC solvents" that they think don't do as much damage,
but they are still CFC's.
