This all sounds good now; LGTM. I still worry about allocating parts of the number-space without getting any further input, but possibly the fact that there aren't any warnings / processes / people scanning for this patch indicates that it's alright. It might be worth waiting a couple of days before landing to see if there's anyone else out there, and/or putting a dedicated announcement on discourse (one imagines not everyone had read the ten or so updates we've done in the same topic).
