In this case, the measure itself is temporary. That's in the text of what we voted on. For it to not be temporary, we'll need to vote on it again.

Also, it only affects Federal congressional districts, not State Senate or State Assembly districts, so there's less feedback: the US Congress has little say over how CA draws its maps.

The effects on normalization are another question that you're right to be concerned about, but I can argue that either way. It's clear who started this mid-cycle redistricting, and it's obviously not actually a response to Joe Biden doing the last census wrong. Credible threat of retaliation may reduce the tendency to break further norms, when compared to the available alternative of not pushing back.
