You are suggesting to convert TrueType/OpenType into big PFB files.
We first thought of that but there is a problem of strategy:

Converting an arbitrary commercial TrueType/OpenType font into PFB
may be considered as violation of license. But PFC is not immediately
useable as such, it is only used to produce temporary PFB files on-the-fly
for immediate printing or PDF production.

Furthermore, for non-commercial fonts, we can include the PFC data in the
OpenType structure and obtain "enriched" fonts which contain the same
glyphs in both glyf or CFF, and charstring 1.

using PFC is a first step to OpenType migration since PFC tables can be
included in OpenType fonts, whenever this is allowed. So we will do that
already for OpenType versions of Computer Modern fonts.

Imagine that in OpenType fonts you can put italic, roman and small-caps
into the same font and distinguish them by "properties". This means that
you can have kerning between all of them... no need for the \/ macro
anymore since we stay in the same font when we write "\emph{and})"...
And these OpenType Computer Modern fonts will be useable by other software
as well, such as InDesign

I know that there is the possibility to write ligatures into AFM, but
afm2tfm does not convert them into TeX ligatures and they seem to be
ignored by all software. And I don't remember when was the last time I
saw such a ligature in a real font. And they are not *smart* ligatures
neither in the TeX sense nor in the OpenType sense.
