What do mean with integration here, to include the syms a 
in-file-lib section, or to integrate gschem with git (or the like) ?

Yes, it would be wery nice to be able to have function blocks both in 
gschem and pcb, and e.g. to be able to use that adj. ldo solution, 
but for 4.3V insted, and gschem calculates the correct resistor values 
(from formulas in the ldo subcircuit) and pcb picks it up complete with 
traces and all (which is done once and for all).

I don't understand you here.

If you would like to discuss subcircuits and the like, perhaps it's
better to start a new thread.
