Seems like the mypy-primer hit is an example of python/mypy#13800. I wonder if it's because there's some change in whether mypy thinks a subclass of str and dict can exist. |

Fixes #10424
Closes #10425
#8465 caused regressions: see #10424 and python/mypy#13800. Since it didn't fix any known problems (just some stylistic nits that we had), let's just revert the PR.
