Prevent user to activate a plugin network wide

[wpfo]

So long we have not Settings API for network_wide activated plugins we need a way to prevent user to activate a plugin network wide.

Possible Solution:
New header in Plugin File Header: Blog
Blog - Boolean. Whether the plugin can only be activated per-site.
If true - Action link 'Network Activate' will be hiden in Network Admin Plugins Table
(problems are the bulk_actions in this approach).

We have now no way to prevent user to activate a plugin network wide.
All 'plugin_action_links' Filters work only if a plugin is already activated.
Or am I missing something?

Alternatively:
we could have only one header for all activation modes e.g.
Activation (or ActivationMode) - String

Network - plugin can only be activated network wide.
Blog - plugin can only be activated per-site.
Both - plugin can be activated network wide or per-site.

What's the use case for preventing a plugin from being activated network-wide?

Wouldn't it be more consistent if we altered the "Network" header to allow

 Network: false (boolean)

to disallow "Network activation"?

I could integrate this into #26925

[cfoellmann]

We could add this to #26909 since the other ticket is a duplicate.

Not a ton of people wanting this. For those who want something like this, a better solution would be to add a filter on $network_wide in activate_plugin() and then have a second plugin that does the limitations, rather than yet another plugin header, thus allowing for more fine grained control.
