So in the present case, you could say

Provides: ppp-plugin-api (= 2.4.6), ppp-plugin-api (= 2.4.7)

and perhaps many or even most future cases could do likewise -
indicating that a bunch of rebuilds / upgrades is not really needed.

Of course you'd also want to relax the runtime version check to match,
and make sure the plugin dir doesn't change (or that you check multiple
plugin dirs).
