I think it would be great to run our test suites regularly instead of only when there's a PR.
For CPython we receive PRs daily, so perhaps there's no issue there. But our bots aren't as high traffic, and depend on various libraries.

Recently in bedevere we discovered issues with uritemplate, aiohttp (and probably asyncio) in Python 3.8. I also realized we haven't been running the tests against the latest Python versions.
