I've requested a block of 5 extension numbers. We already have two concrete extensions that we need ids for. Our project is under active development and we can imagine a number of other extensions that we will want in future, so we thought we'd start by registering a block of 5, instead of raising a new PR here each time we need a new one (#8772)
