This is a use case for -m that requires adding the working directory
to sys.path. I work in virtual environments, and I don't navigate into
a package and execute modules. The target package is always either in
the standard library or installed in site-packages, and the module is
executed from the top level. So for me adding the working directory is
a feature I never need, and I completely forgot about why anyone would
want it.

Having the working directory added when using the -m flag is something I use in quite a few of my project. See https://aroberge.github.io/friendly-traceback-docs/docs/html/usage.html for example (example usages 3 to 6 rely on this).
