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)

Also from mapfile/mapline(s) it is possible distinguish if font is Type1
PFB or bitmap PK (bitmap fonts are not present in mapfiles). And bitmap
parameter must be correctly passed to fontloader otherwise font will be
not loaded.
btw, A map file as defined by an environment variable is loaded after
the font is defined i.e. when the file is finalized; \pdfmapfile will
load directly but in that case you know what maptile and therefore also
know its content and can define accordingly .. not much different from
pdftex etc.
