Me neither. I think you are safe to go with it.

I guess no, it cannot be. That is for building the project
interactively, and it is not targeted for packagers. We do not use
Haskell Stack for packaging, that is more intended for development.

Yes, the .cabal file can give you the immediate dependencies, but not
their (transitive) dependencies.

Yes, that is right.

We always keep the .cabal file as the hs- ports still rely on the
Cabal library to drive the build process. Basically, what we have in
the ports tree is just a moderately thin layer of wrapping all around
this.

For what it is worth, you do not need to use the hsporter -- I usually
copy the files for one of the already existing hs- ports and change
their contents for the new port, it should be intuitive (but please
poke use if not). hsporter will not create ports for the dependencies
anyway, you will have to do it yourself. As far as I recall,
bsd.cabal.mk is helpful enough to tell the port of which Cabal package
is missing on trying to build the port, so you can do the porting
incrementally by always adding them to the fold (until you reach ports
with no further dependencies).
