This addresses https://meta.wikimedia.org/wiki/Talk:Community_Wishlist#Technical_question:_naming_of_wishes let's introduce numerical titles in the form W[1-9][0-9]*
We can do it in a similar way to how wikibase does it i.e.
- store the latest id in a db table (wb_id_counters for wikibase)
- when you're creating a new wish get the latest id, add 1 and update with the new value inside a transaction
- and then create the new page with W<the new id> as the title
When this is done we'll need to figure out how to migrate existing wishes (but note this is worth doing even if we do not migrate them)
