That wont necessarily save it, my impression was that google was going to attempt to heuristically detect other yt interfaces and mess with them. I.e: "You keep downloading video data, but havent hit our ad endpoint at all, gtfo"
Revanced would hit the same heuristic i described. We will have to see how it all shakes out, although my bet is on some temporary interuptions, followed by the apps working around them.
