Many of our loggers currently return generic Tasks in order to support interception, incurring lots of needless heap allocations. For example, RelationalCommand.ExecuteReaderAsync calls CommandReaderExecutingAsync and CommandReaderExecutedAsync, both of which actually return synchronously in almost all cases but allocate Task instances.

In addition, our interceptor API surface also returns generic Tasks from all methods. This means that the moment an interceptor is set up, the user starts paying additional allocations for all of its methods, regardless of whether those are intercepted or if they complete synchronously.

As this is a (minor) breaking change in a relatively new API, it may be good to do this early.

@roji @smitpatel What I meant to do was remove the milestone and reopen the issue so we can discuss again in triage since it was already reported as a break.
