Excluding other extensions when an extension is present

[zhouyx]

Right now we have some extensions that don't work well together. For example when <amp-skimlink> and <amp-link-rewrite> works together, the ladder component can affect what the previous component does.
It would be useful to have a feature that only allow one component on a page among a list of mutual exclusive extensions.

When discussing this I was thinking of requires_extension and that perhaps we should also have a excludes_extension feature. This is to be more explicit than satisfies, requires and excludes.

[zhouyx]

I agree. excludes_extensions is also much easier to understand : )

+1 for excludes_extensions

amp-access and amp-subscriptions are mutually exclusive.

@zhouyx I think this got forgotten. Is this still important to you?

[zhouyx]

I think the issue still exist. But I not urgent because there's no incentive for one to include two components either from different service provider (amp-skimlink vs amp-smartlink) or designed for the same purpose (amp-access vs amp-subscriptions).

Thanks for the update. I'll keep it around, but let it remain at P3 for now. Would be nice for a fixit.
