Not sure if there are _important_ use cases (that could justify certain
design decisions), but I can certainly imagine using a non-debug (and
therefore faster) Pandas or NumPy for preparing some data that I need to
debug my own code. More generally, whenever I can avoid using a debug
version of a *dependency* that I don't need to include in my debug
analysis, it's probably a good idea to not use the debug version.

Even given venvs and virtualisation techniques, it would probably be nice
if users could install debug+nondebug versions of libraries once and then
import the right one at need, rather than having to set up a new
environment (while they're on a train in the middle of nowhere without fast
access to PyPI).
