Are there use cases where you only want to load some debug extensions, even if more are installed?

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).
