Supposing the latest FC3 bind package is 20:9.2.4 (I'll trust Enrico on
that). To the best of my knowledge there is no security or serious bug
in that version and therefore nothing for the Legacy team to concern
themselves with.

As far as rpm is concerned, version 20:9.2.4 is newer than version 9.3
(i.e. 0:9.3) and hence would satisfy a dependency of:

Requires: bind >= 9.3

However, the pacakge using this would not build/work because it actually
requires version 9.3 or later, which version 9.2.4 is not.

To make sure that the problem just described did not happen.

Who said anything about 9:3?
