The developers did not feel that separate coupling was required, and it was
increasingly difficult to maintain the old code that tried to figure out what
was "solvent" and what was "solute". It would not be hard to re-introduce a
facility for two heat baths, if that is desired. Take a look at the code
for LES simulations, where separate temperature couplings are implemented.
