I've been comparing a few of the tfm files with their
CM counterparts, because that is something I am used to
doing.

 From the computer modern set:

lmex10.tfm  % identical
lmmi5.tfm   % identical
lmmi6.tfm   % identical
lmmi7.tfm   % identical
lmmi8.tfm   % identical
lmmi9.tfm   % identical
lmmi10.tfm  % identical
lmmi12.tfm  % identical
lmmib10.tfm % identical
lmsy5.tfm   % extra chars: 254,255 (octal)
lmsy6.tfm   % extra chars: 254,255 (octal)
lmsy7.tfm   % extra chars: 254,255 (octal)
lmsy8.tfm   % extra chars: 254,255 (octal)
lmsy9.tfm   % extra chars: 254,255 (octal)
lmsy10.tfm  % extra chars: 254,255 (octal)
lmbsy10.tfm % extra chars: 254,255 (octal)

 From the 'AMS' set:

lmmib5.tfm  % identical
lmmib7.tfm  % identical
lmbsy5.tfm  % extra chars: 254,255 (octal)
lmbsy7.tfm  % extra chars: 254,255 (octal)

The two extra characters are:

   /lessorequalslant
   /greaterorequalslant


There are no lmbsy9,8 etc., so changing the mappings in
type-enc has to be done with a bit of care, but besides
that I see no problem in the metrics.

Best, Taco
