[serve] Remove warnings for upcoming default change (#44051)

This is unnecessarily spammy for multiple releases. We will do the following:

- Add a warning in 2.10 release notes about upcoming change.
- Next release (3.11) we'll change the default and log a warning if default is used.
- In 3.12 we'll remove the warning.
