DI Exporter Pro, problems?

I've been using this exporter for quite some time. It does seem to have occasional issues with sequences, although if they're setup the old way, they work fine. Otherwise, I have no troubles at all, and the export itself is magnitudes faster than the original exporter.
So... my Q is; Why do some of the pros around here recommend _against_ it? Am I missing something that's going to come back and bite me?
