He didn't say, so it's hard to be 100% sure. I'm sure we could both come up
with unlikely and marginal circuits that could misbehave given a 50%
difference in characteristics in the aforementioned areas. Heck, you can
even use them as varactors, in which case the junction capacitance
is very important (though it's not guaranteed in any case).

For use as a rectifier at <1kHz, and for many other common uses, may as
well consider them the same, even though there ARE the two distinct types.

There are people who use them to make HF Cockcroft-Walton voltage multipliers,
in which case it might pay to look a bit more closely.
