For internal use (e.g. inside a corporation that bought heavily into ActiveX, etc) you're going to have a hell of a time getting authorization to rewrite things because "it works just fine and we don't feel a need to spend money on this" That's not changing any time soon; even with old IE ripped out of Windows 10 to a large extent, there are still multitudes of kiosks and other custom setups using XP/Vista out there that won't be getting any upgrade.
