Current plan given web incompat

[syg]

Given #28, #31, #32, it is clear that the item name is not web compatible and will not work. #32 especially is the nail in the coffin, given Flickr's breakage.

Going forward, my plan is, at the Nov 2020 meeting:

1. Propose a rename the proposal to at.

Please bikeshed in #33

2. Re-open discussion for splitting out String.prototype.at.

There is no new information, but many delegates were unhappy with the lack of discussion and time devoted to the topic. At the next meeting, I will ask for a bigger timebox to discuss the possibility of splitting out String.prototype.at into its own proposal.

We reached consensus to rename to .at() and to check if it's web-compatible. Additionally, we reaffirmed consensus that the method remains included on the String prototype via String.prototype.at.
