A key difference is that the CM fonts source need not be installed
(tetex automatically runs METAFONT in some cases, but it could easily
be pointed at different source names).  

Users use *.tfm files when running TeX, and the restrictions on *.mf
names are not restrictions on *.tfm names.  That's a key fact.

However, the LPPL restricts the actual filename the user normally
uses, rather than a name that really appears only in the source.
