A lot of Youtube videos I saw don't have AV1 option (check with yt-dlp --list-formats). So are they going to re-encode everything now?

It is a certainty that, some time in the future, the bandwidth cost of not re-encoding will exceed the one-time cost of re-encoding.

How far in the future probably informed this decision.

They might. Especially if they are popular.
