How to be disable module per environment?

Sometime we are using modules that are useful only for local developments. For example Ho_Templatehints or MSP_DevTools.

Most of the time we are installing them with composer running this command

composer require --dev module/name

On production environment we don’t want to have any dev packages so during our deployment process we install all required packages with composer install --no-dev. Problem with this solution is that if we have some modules enabled in config.php command bin/magento setup:upgrade will fail.

To avoid problems on production we can simply modules key to env.php.

Original config.php

return [
    'modules' => [
        ...,
        'MSP_DevTools' => 1,
        ...
    ]
]

and our env.php

...
'install' => [
    'date' => 'Thu, 11 Oct 2018 18:21:31 +0000'
],
'modules' => [
    ...,
    'MSP_DevTools' => 0,
    ...
]
...

I would like to end with one important remark : after running bin/magento setup:upgrade file config.php will be updated with value from env.php. So in our example at the end in both files we will have

'MSP_DevTools' => 0

There is open ticket in community features so we can expect that at some point someone will add this feature to Magento functionality.
