Problem is that there are no AFM files for CSFonts (and IIRC never

TFM files) and some subset of CSFonts (those which are often used) were
later converted to Type 1 variant... Probably nobody generated yet AFM
files for CSFonts as they were not needed, TeX handle just TFM files.
with an afm file one can also use the fonts in other applications than tex
So if AFM files are really needed and combination PFB+TFM plus MetaFont
source code is not enough, how to correctly generate AFM files?
manual, its a text file
And why cannot be still used TFM files which contains all kerns and
ligature information?
because one then also needs an encoding vector (an enc file is actually
a blob of postscript, kind of weird as it could also have been a list)
I'm speaking ConTeXt now: the reason for not bothering about tfm (but
use afm instead) is that we can use *all* glyphs in a font, not just as
subset and that made it possible in the early days of luatex to use
type 1 fonts without bothering about encodings (we only use tfm in
context for traditional math fonts).
