I would suggest that these be ?= assignments.

Rationale:  There is more than one Sourcery toolchain out there, and
they sometimes differ in these.  It'd be nice if a hypothetical vendor
using a hypothetical custom variant of the Sourcery toolchain could use
these configuration files with nothing more than a few variable
assignments.  :)

I do quite like the cleanup.
