Good change in principle, but I think "base" and "append" are not a great
choice of names for the parameters. Probably not very intuitive for users.
How about calling them `default` and `additional`?
While at it, should we also rename the `ALWAYS_PARENT_FIRST_LOADER` config
key name? Calling it `CLASS_LOADING_PARENT_FIRST_PACKAGES` or
`CL_PARENT_FIRST_PATTERNS` seems better.---
