Amphtml: [MASTER FEATURE] Enable use of AMP Components outside of AMP pages

[nainar]

Explore the idea of using AMP components in non AMP pages.

Potential benefits:

• Currently developers have to create a new stack to work in AMP, this adds not just development overhead, but in some cases increase engineering teams (if they decide to use the paired AMP approach).
• By being able to use AMP components outside of AMP we are making incremental adoption possible rather than require a complete change/addition in infrastructure.
• AMP doesn't support a full range of experiences yet, due to lack of component availability e.g. payments, VR experiences.
• Any significant improvements that we have made to components (e.g. amp-img not triggering reflow after network request, social AMP embeds allow for a single interface, amp-list allows for dynamic lists without JS payloads that may be render blocking) are tied to the AMP ecosystem

@cramforce does this need to be discussed at TSC? This was mentioned as one of the first potential decisions to be made

[cramforce]

@ssantosms yes!

[nainar]

Hi @ssantosms and @cramforce ! Does the discussion entail a high level discussion of the idea or a more in depth design review as well?

[cramforce]

Since @dvoytenko is the primary designer of this, he can just bring it up casually, and then we can see what process to follow.

This is the master issue for Bento AMP?

[nainar]

@westonruter yes it is!

Just curious if there is any development on this.
