multisite-setup, setup.php `plugins` key does not allow disabling plugins

[drzraf]

https://github.com/getgrav/grav-learn/blob/develop/pages/08.advanced/05.multisite-setup/docs.17.md
indicates that user/setup.php could do something like:

return [
    'plugins' => []
];

I tried:

return [
    'plugins' => [
        'problems' => [
            'enabled' => 'false'
        ],
        'git-sync' => [
            'enabled' => 'false'
        ]
    ],

... in order to disable a set of plugins, without success.

Whether or not this is supported, this must be documented.
Note: I couldn't find the necessary codebase references to dig for the underlying logic.

Setup is not meant to do that. It just initializes the system so that everything loads from the right place -- including the configuration. Configuration files that get loaded later will override everything in the setup.

[drzraf]

Yeah, but it's documented it could already do that (= configure plugins):

So one would expect it could disable plugins too.

[mahagr]

No, even that won't work if you override the keys. Besides above example has been superseded with a better solution anyways.

Could you please remove that misleading chunk from the documentation and put the better solution? I'm interested knowing what best practices are advised.
