I have certainly found some discrepancies in the past. If you never
reason about partial or infinite values you're not likely to stumble
over these inconsistencies, though.

If you're a GHC user worried about partial/infinite values you should
be aware that the GHC team now and then chooses a pragmatic solution
instead of an exactly correct one.
