Could be that this is the case for \setlefrightkerning, but AFAIK
it is not for low-level \setkern commands.  

Anyway, I can see that introducing glpyh name reencoding hacks at 
the ETX level is a rather controversial issue, since it is sort 
of an abuse of the original concept of ETX files to describe an 
encoding and nothing else.  Still it would seem useful to me to 
be able to manipulate the way a source encoding is seen not only
when reading fonts \frompl{<font>} but also in \fromafm{<font>}.  
Hacking the AFM files, as you suggested on another occasion, 
certainly doesn't seem to be a proper solution either.

Cheers, Ulrik.
