It doesnt need to be maintained, it only needs to work in one commit on
master and then one uses time-machine to rebuild the bootstrap binaries
if they wish to. The make-bootstrap code is already unmaintained for
every architecture anyway since we never rebuild bootstrap binaries
using later GNU Guix revisions ever.

I'd like both but little endian has the widest eco-system support
especially w.r.t. to Linux drivers. Many Linux drivers have endianness
bugs (lack of endian-safe serialization for DMA..), it's such a plague
that sticking to little endian is just better right now. One common
example being mpt3sas and amdgpu drivers required in some
configurations of the Talos II system.
