I see, so my (dummy) primary file could just a small text file
saying "This is a BLAST protein database." or similar - and
that would let me reproduce the current behaviour?

The only possible downside I can see right now is wondering
what happens to existing histories containing old BLAST
databases created with the current code... but that will sort
itself out eventually with some user inconvenience.

Who is the composite file architect (for their thoughts)?
