New description:

 This has been going on for the last couple of versions. I develop themes
 with XAMPP locally and when I install a fresh copy of WordPress (eg: 6.1
 now), then turn on debug, I get inundated with "Deprecated:" notices. For
 example, fresh install, go to Plugins, and you might see them (see
 screenshot); install and activate a plugin, such as Classic
 Editor...sometimes the notices disappear after several refreshes.

 I get these notices all the time with debugging on, which makes it
 difficult to test/debug themes.

 Examples:

 {{{
 Deprecated: Return type of Requests_Cookie_Jar::offsetExists($key) should
 either be compatible with ArrayAccess::offsetExists(mixed $offset): bool,
 or the #[\ReturnTypeWillChange] attribute should be used to temporarily
 suppress the notice in D:\...\wp-includes\Requests\Cookie\Jar.php on line
 63

 Deprecated: Return type of Requests_Cookie_Jar::offsetGet($key) should
 either be compatible with ArrayAccess::offsetGet(mixed $offset): mixed, or
 the #[\ReturnTypeWillChange] attribute should be used to temporarily
 suppress the notice in D:\...\wp-includes\Requests\Cookie\Jar.php on line
 73
 }}}
