The solution I found easy is my devmap script: I can use the generic 
symbols with letters, then I attach a devmap attribute telling which
actual device and footprint shall be used (e.g. bc817_sot23) and the rest 
is done while converting from gschem to pcb. Actual device maps are plain 
text files that describe attributes to be added/overwritten with a pinmap 
functionality that can replace pin numbers by value (so that pin C becomes 
pin 3). Device maps are easy to write, easy to maintain and VCS friendly. 
Schematics with the above "bc817_sot23" next to the symbol are readable, 
still not overtaxed with extra text.
