Hi,

The main reason why I think we should get all of the three states is we
don't know exactly if those plugins (which developer didn't specify) are
compatible or not, so we should not make any assumptions and prevent
the user from enabling any plugins she/he wants. The best we can do here
is to provide all of the information plugin developer knows, directly to
the user,
without us in the middle who make decisions based on incomplete data.

So lets ask plugin developer to specify a set of components which he tested
his plugin with. Plus a list of components which he tested with and he is
sure
that those are not going to working together.

On UI we can show explicitly, that this combination is tested and approved
to
be working, another combination is not working for sure (plugin developers
tested
it and explicitly specified), and there will be a lot of combination which
are going
to work together without problems, but we should say the user, that the
developer
didn't test it and he should test and use it carefully.

Thanks,
