But yum-builddep does evaluate them.

Which is nearly what I've been preaching. "The spec file's BuildRequires
become the src.rpm's Requires" depending on the environment the src.rpm is
built within.

And why collect "what build-requires were active during the creation of that
specific src.rpm file" even when building a src.rpm with --nodeps?

That's friendly from you. I think they don't serve a useful purpose,
if one must "recreate" them or ignore them in favour of working with
only the spec file contents.
