Terrible why? Bookmarklets and XSLT (and things like Greasemonkey userscripts) were some of the things that made the web more "read-write" in the '00s: anyone could remix web content however they saw fit, optimizing it for their personal use-cases, and often attracted kids and "normies" to coding.

Even today, they can be used to do stuff that most people find magical. Unfortunately they are unfashionable, so they're slowly getting strangled by the big players who want to have all the control all the time.
