Payment Handler API (defer)

No description provided.

I thought that we only used defer if we decided not to look at something. From the description it seems like we looked at this quite a bit and therefore non-harmful seems more appropriate.

#23 is closed, should this pull request instead be referring to #390? If so, that issue still needs a clear summary rationale in the issue itself which is then reflected here. If not, how do we close #390?

[tantek]

We need to:

• ✅ re-open #23
• record the reasoning for a new position of "non-harmful" in that issue, and then
• update this pull request accordingly, referencing 23 to re-close it.

Accurate update.

I've rebased this to match current conventions. But #23 has recent comments. I'll wait a bit with merging to avoid flip-flopping.

The comments above suggest neutral (previously called non-harmful), and #23 (comment) also seems neutral (mildly positive on mobile, mildly negative on desktop).
