There are browser plugins like Greasemonkey or Tampermonkey that manage these kind of patches. I'm often removing some "functionality" of a website I visit often (e.g. removing annoying chat boxes) There are also repositories of scripts like GreasyFork (https://greasyfork.org https://greasyfork.org). I suggest that maybe your script could be ported to Tampermonkey instead of distributing it as a bookmarklet.
