The basis of this work comes from pretty much all SD/MicroSD cards, most
consumer USB hard disks, etc being preformatted as NTFS/exFAT. When building a
consumer device the designers often want to just use FUSE out of the box so they
don't have to work on adding the functionality themselves.
meta-oe is often times too much stuff in one bundle to just included in a
project. The developers I work with prefer a smaller load of packages,
primarily oe-core + whatever they need. It makes it easier to support and
easier to prevent problems from being introduced by feature creep.

Yes they could, but then it forces more people to copy the recipes out of meta-oe.
I myself am mixed on if fuse belongs on oe-core or not. I can see the argument
both ways on including it or rejecting it. However, I'm getting more and more
commercial requests for FUSE to be part of the main system.
