This sounds like a great idea, although a long-term one.

For instance Manhattan could provide flag "1".  Nukes would require flag
"1" to be built.  Apollo would provide flag "2", which is required for
building of all spaceship parts.  These flags are not hard-coded but must
simply match between providers and requirers.

Having them be alphabetic rather than numeric would be easier for ruleset
authors.  The alphabetic flags ("can_build_nuke", "can_build_space") can
be converted into a numeric value (0,1) at ruleset load-time and
henceforth used solely as a bit-vector.

But, this does not have to be done immediately.
