[adam-grant-hendry]

What's the problem this feature will solve?

Reading here, it says:

We intend to make importlib the default in future releases, depending on feedback.

However, I don't know where to provide feedback.

Additional context

I've used --import-mode=importlib successfully and I think it should become the new default!

[adam-grant-hendry]

Similarly, the note here says:

The new --import-mode=importlib (see Import modes) doesn’t have any of the drawbacks above because sys.path is not changed when importing test modules, so users that run into this issue are strongly encouraged to try it and report if the new option works well for them.

but doesn't state where to provide feedback.

The issue is in #7245, however at this point it is clear that we should not change the default, as importlib has its own set of drawbacks and changing the default would severely impact a lot of test suites.
