Those conditions [on cm fonts] _are_ at the level of individual file
names.
You can not call your font metric file cmr10.tfm unless it is byte for
byte the same as Knuth's cmr10.
Unlike the LaTeX version of this rule which has, as far as I know, never
been "used in anger" Knuth has in the not so distant past used this rule
to explictly force the withdrawl of some modified font metrics that
were being distributed with some linux distributions.
The modified metrics "improved" the interletter spacing in some cases,
and at the same time destroyed the use of TeX as a portable document
system.
