I'd really prefer to have CertainPerformance host this somewhere. This Gist exists to give people an easy single-click to install. I'll try to keep it updated if there are any changes to the code in that Stack Apps question. If there are changes which are not reflected here, please ping me on that question, or leave a comment here.

If CertainPerformance does host the file somewhere, my plan is to update this to have userscript managers start looking at wherever that new location is.
