They are a bit orthogonal actually.

This serie addresses the build failures we have today in order to
still be able to build binaries that work.

The FAT transition is more of a longer-term goal in order to not have
the size restriction we have eventually (hopefully 2018.05).

So the first one mitigates the problem, while the second one allows us
to get rid of the problem entirely in the future.
