Comment:
I can see a couple of groupings that may be useful for defining subpackages

- APT/DPKG stuff: `apt+`, `deb`, `deba`, `debd`, `dpkg+` (how the hell is there 5 of them?)
- RPM stuff: `rpm`, `rpms+`, `trpm`
- things we don't have all the bits for: `bpp`, `hp48+`, `uace`, `ualz`, `uarc`, `uarj`, `uha`, `ulha`, `uzoo` (ARC here *might* be the same format as what PKARC was for?)
- git-related backends: `gitfs+`, `changesetfs`, `patchsetfs`
- misc, shared-depends backends: `mailfs`, `patchfs`, `lslR`
- archive file formats: `u7z`, `uar`, `ulib`, `unar`, `urar`, `ucab`, `uzip`
- disk/etc image formats: `iso9660`, `uc1541`, `uwim`
- hard to categorise backends: `a+`, `audio`, `s3+`

**EDIT:** This approach got dropped in favour of simply documenting what packages are needed for the extfs scripts
