Agreed, its gotta happen, and the sooner the better.
Since its gonna be a disruptive change it should be made in a branch first, say `new_scintilla` then when its ready, mainline becomes LTS for anyone who wants to support it (I suspect nobody) and the `new_scintilla` branch becomes mainline.
If you want to start it, you can make a branch, so knock yourself out :grin:
