How about fedora-secure-system have
Conflicts: flurble <= <vulnerable version>  # CAN-9999-999

If a package is known to be vulnerable, it conflicts with a secure system.

Wouldn't that accomplish what you want?  It will install in the absence 
of flurble, but if a vulnerable version is installed, it will (should?) 
cause an upgrade.

Hmm.... And if there is no upgrade available, maybe a remove... In fact, 
I kind of like that idea.  Update fedora-secure-system immediately upon 
disclosure of a problem, even in absense of a fix.  Sysadmins can decide 
to uninstall or remain insecure based on whatever their constraints are.
