I don't think this optimization is needed. If it is a term, the previous logic would ask isClass and then isType and then return false. Both of these calls are extremely cheap. So, no need to complicate the logic in this case.

This construct is logically correct but mixes two concerns. I would suggest to something more along the lines of what we had:
if hasExport(rest) then
process(rest)
exported

Fixes #15944
Fixes #24879
If exports added members, then check for more constructor proxies.
Follow up previous tweak for using constructor proxy of exported member, by preserving its prefix.
Although
needsConstructorProxiesis not expensive, it's also cheap to exclude terms first and save calls; there are many more term members than types.
