For me µsort is a non-starter since it doesn't ignore the import/from part when sorting lexicographically. So when an import changes from `import foo` to `from foo import bar` (and vice versa), the import is moved. Sorting should start at the package name, nothing else.
I suspect you are fighting the tide of common practice in the Python community. In your example, switching from `import foo` to `from foo import bar` is changing the entire nature of the import. Sorting module- and from-imports separately also makes it much easier for many people to visually scan a block of imports. And similar to black, having a tool be consistent and predictable across projects and modules is more important than bikeshedding every possible opinion.
