Yes I get that, I think there is a new DH for almost every message, much better than TLS. The problem is we have no idea what the NSAs abilities are in terms of actual cryptanalysis/cracking, but we do know that they have an immense desire for it.

RFC 3526 puts the low end of the 1536 bit group's strength at 90 bits. If some unknown weakness was found that lowers that significantly that doesn't leave things very safe.

Agreed that curves would be ideal.
