Correct.

Yes, that's one plan, *if* someone can sort out, or is willing to
shoulder, the perhaps illogical but still worrisome surroundings of
FatPkg / FatBinPkg.

(I don't intend to spread FUD!)

For example, if your employer authorizes you to implement GplFatPkg from
scratch, and distribute it as an external module, I -- as someone
without any education in law though -- will give you a standing ovation
and buy you a case of beer at KVM Forum 2013. Deal? :)

(You proved to have great leverage by getting the efi compat table
extended, so... :))

Right. Eg. Shell1 is embedded as a pre-built binary, but that's just
"convenience", you can build the in-tree Shell2 from source afresh and
embed that instead (and ship its source too).
