Make `warn` deprecation note a comment instead
What does this MR do?
We realized that issuing deprecation notices via Kernel.warn
is quite noisy, as they also surface in tests, and since furthermore we already have a dedicated issue to migrate these functions over in #207989 (closed), it is probably safe to just make this a comment again, as it had been initially.
Does this MR meet the acceptance criteria?
