Fwiw the answer to that is certainly no. The only caveat is that some
platforms have not entirely complete implementations of IEEE missing
corner cases such as denormalized values but I don't think that would
be something that would be changed with a different hash function

Personally while I would like to avoid code that actively crashes or
fails basic tests on Vax even I don't think we need to worry about
replication or federated queries in a heterogeneous environment where
some servers are Vaxen and some are modern hardware. That seems a bit
