There is a long time running debate about the fact that ConfigureAwait(false) should have been the default behavior, now I understand it's late to change the default await behavior, but what about introducing a new operator like awaitf (note f char) or a similar concept, that act as a normal await with a ConfigureAwait(false) behavior?
In my example the f char stands for "free" in the sense that it's not capturing context, but my point is not about the real name but about the concept of having an operator that explicitly define the behavior.

This has the pros of having a clear intention while at the same time being backward compatible

what do you think?
