The problem at this point isn't whether chrome will disable it... It can be added back, probably fairly easily as google intents to keep it around for "enterprise" anyway, so it's probably just gonna end up changing/removing one if-statement. If not, then the code already exists and has to be merged back in. The problem is distribution of the actual extensions, as Vivaldi kinda pointed out, as the other browsers most…
We need a third party extensions store.
These companies helping Mozilla getting Servo into shape would be a really good idea, which is why they won't do it.
