A few obvious ones that come to my mind are that you should be able
to write a new merge strategy and link the resulting binary into Git
without much hassle.  You might even want to make that a dynamically
loaded object.  The interface into a merge strategy is fairly narrow
IIRC.  Or possibly a new remote helper.

Adding a new refs backend may need to wait for the work Patrick is
doing to add reftable support, but once the abstraction gets to the
point to sufficiently hide the differences between files and reftables
backends, I do not see a reason why you cannot add the third one.

And more into the future, we might want to have an object DB
abstraction, similar to how we abstracted refs API over time, at
which time you might be writing code that stores objects to and
retrieves objects from persistent redis and whatnot in your favorite
language.
