I suggested it because I misunderstood what you were talking
about by cell clustering rules.

I thought that the topic under discussion was further variations
within each encoding - like where combining glyphs were located 
relative to the origin.

(I also thought that there was the suggestion to detect Solaris fonts
by looking at the foundry/family and use wtt clustering rules
for them, but probably I just misunderstood that as well.)

So, I'll take the blame for mad suggestions, but blame it on
confusion :-)
