Awesome!

As a further improvement, is it possible to configure multipathd to read
from a custom configuration path? That way we could, e.g., dump the
required multipath.conf in $TMPDIR instead of requiring the system-level
configuration.

If not, can you please make the group_requires automatically make the
symlink instead of requiring it? Obviously checking if there was already
a prod config file there.

I also had to apply the following patch:
