The release instructions say to put the internal only changes in the PR description. That makes for an awfully noisy commit message in the logs that serves no purpose that I can see except to re-capitulate code review conclusions. We do that for no other code review conclusion afaict.

Perhaps there is reasoning I'm missing.

Feel free to update it to instead be a comment on the PR. Agreed, no need to be in the actual PR description - the intent was solely "document them in the PR so that it can be discussed."

Thank you! I appreciate you splitting out those deprecation removals into dedicated PRs.

[Eric-Arellano]

Probably better in new feature, but this works too.

[jsirois]

As I understood it this was a stopgap bugfix that would be replaced by better handling with no special feature / configuration use needed going forward.

[Eric-Arellano]

That's how I viewed it at first too, but Benjy conjectured it may always be worth keeping if the performance is better. I removed the help message saying "we plan to deprecate this" after review feedback.
