Should we have something like ERC (Ethereum Request for Comments, like the IETF's RFC https://www.ietf.org/rfc.html) ?
Or do we want to somehow expand the notion of EIPs to include them?

The items in https://github.com/ethereum/wiki/wiki/Standardized_Contract_APIs are top candidates for ERCs.

https://en.wikipedia.org/wiki/Internet_Standard

Then down the line (could take a while), some ERCs could be ESDs (Ethereum Standards).

This is relevant now, since token "standards" are being discussed quite heavily:
