Not quite ;-)

Sounds very promising indeed! As Patrick mentioned in his tablature test 
file,
a tablature key (i.e. string labels indicating the pitch) would be a 
useful enhancement.

I didn't dig very deep, but how complicated would it be to allow note 
names for
string tunings?

For standard situations, the music function \makeStringTuning will work, 
and we could save the
note names for later use within a tabKey. On the other hand, if the 
tuning is given in the
numeric way, the corresponding note names (at least with some tunings) 
will be not unambiguous.

So IMHO, while the latter solution will be easier to implement, the 
former proposal
is more extensible for the future.

Just my 2ct
