LGTM, but I'm holding it back until the feature freeze has actually passed, on the rare chance that we still merge another feature today.

[yardenshoham]

I think it's time

[delvh]

No, there are still two hours until feature freeze (https://discord.com/channels/322538954119184384/537668686173962260/1074769294090579998).
Especially #21563 could potentially still be merged.
However, I haven't reviewed the PR yet, I don't know if it is ready, so I'll leave it to those that reviewed it.

[yardenshoham]

I have to log off now, if #21563 gets merged feel free to push to this branch/replace this PR
