Comment:
Making dash bash breaks all scripts with bash shebang, installing nvim before vim makes it the default provider for the vim alternative group which you can easily fix with xbps-alternatives, avoid by installing vim first (instead of alphabetically sorting xbps-install arguments or by just not installing nvim. It also doesn't break half the system, all it does is make the cursor werid on your system.

There would be no point in alternatives, if the requirement would be that they are 100% compatible, some things have stricter requirements than others, like shells, while other more interactive programs don't.
