The URL length limit seems pretty reasonable, especially since the URL is a highly user visible component, so overly long URLs annoy/harm users much more than web devs (just think of pasting this super-long url into chat or company wiki!) In particular, I think the URL should be copy-pasteable at all times, and according to your google's link, that means 32KB limit. I'd lower it to 8 KB just to be safe in case there is URL encoding involved.
