indeed, and there is no reason to consult them as map files/lines are
a resource managed in sync with fonts (and in a modern luatex font
setup they are not even needed)
I was thinking about choosing ENC file for 8bit PFB fonts from this
database instead manually searching for correct ENC files... As now it
is possible to use TFM+PFB+ENC fonts files via loader. And pdftex.map
provides needed database for it.
that is something different ... mapfiles are explicitly loaded with
\pdfmapfile or taken from an environment variable ... they kick in very
late in the backend (finalizing document)
if you really want to do that you can write some lua code that looks at
the relevant variable, and then parses the map file(s) it returns
(also, given the small amount of type one files that one would possibly
want to load in a luatex setup one can as well make a dedicated database
- or lua table - for it as it only involves a few files)
(and in the loader you probably can do without the enc esp for cs as
it's one to one with the built-in default anyway)
