There's a closed pull request on the void-packages repository

[RFC] mc: cleanup, python3, adopt.
https://github.com/void-linux/void-packages/pull/38079

Description:
This PR splits off python-dependent backends into a subpackage. This is the approach used in other distros.
However, this only takes care of having python, it does not take into account more programs that may be needed (like the uc1451 backend needing the `vice` package). Most backends are just thin translation layers over an external tool, and some need perl. None of those dependencies are marked as such in the package, nor are they in other distros. What would be the best way to deal with that?

#### Testing the changes
- I tested the changes in this PR: **YES**
    It is impossible to test the s3 backend without an AWS S3 account, but the patch is used in other distros.
