rpm has never supported "dual signing" if you mean signing with 2 different 
keys.
While there were ways to sign twice, with different algorithms, which ended up
in different tags, only one of those signatures was ever verified.

It doesn't make much sense to have multiple signatures, you are better off 
using a longer key or hash.

What exactly is "dual signing" to you?
