Trying to create a short url I ended up on this wiki-404 page that shouldn't be.
@Ammarpad: I am not aware of any plans (apart from vague ideas), could you please point to them?
I found T187045: Code Stewardship Review: ShortUrl Extension, maybe that is what this task should depend on (and be marked as stalled)?
To be clear, any short URLs created using the ShortUrl system (/s/) will be supported forever: we don't break working URLs. We do however plan to stop the creation of new URLs in favor of w.wiki.
If there are specific features in the old system you/the communities you're in depend upon that aren't in the new one, I'd like to hear them and figure out how address those needs. T187045 is a good task for that.
