I usually used the term "conventional histograms". I think it works
well, but it might not age well. (In 10 years, the native histograms
will feel pretty conventional to most users. On the other hand,
perhaps the old histograms are so rarely used them that we won't need
a name for them so often...)
Besides "non-native" (which I think is a fine name), you could call
them "emulated" or "legacy". We can see what name will stick.

You can always open the naming discussion (again), but it was already
confusing to change from "sparse histogram" to "native histograms". I
expect throwing in yet another term will multiply the confusion.
Having said that, I like "dynamic" much more than "sparse", but it
still suffers from the problem that it describes just a subset of the
features, while "native" describes the fundamental change that enabled
all the features that the other names describe ("sparse", "dynamic",
"high-res", "exponential", ...)
The only problem I have with the term "native" is that the old
histograms were already "native" in the old protobuf format, only that
Prometheus never delivered that promise when ingesting.
As a different thought: "static histograms" might still be a good name
for the old histograms, even if the new ones are called "native"
rather than "dynamic".
