Yes. You didn't address my question directly though, so let me ask it
again: where is this %location field access (named "location") used? It
seems nowhere. Thus, we can simply rename it without impacting
anything, right (except theoretical usages in the wild, since in the
API).

No. If we revert something, it won't be that whole commit, but just the
moving of the field in the define-configuration produced record.

Why do we have to massage the user facing record
(namespace-configuration) instead of the underlying mechanics? The
macro should serve us, not the other way around :-). See my idea to
simply rename/remove that automatically produced "location" accessor
which appears unused to me. Would that work?
