Quite the opposite: this page makes it rather clear that oversampling is
a kind of resampling, with specific settings to ensure particular
properties of the spectrum.

As such, it should go into the generic resampling filter (or even
library), enabled by options. That way, it is available not only
explicitly from expert users but also automatically, when filters
declare specific samples rates.
