I haven't decided if I'm in favor of this feature yet but I asked the same
questions as you when the pull request landed. This gist served as a good
illustration of possible benefits
https://gist.github.com/marcioAlmada/12ef23038bcf5acaa2e2f6b808c968d3.
Boilerplate measuring apart, it seems logical that a closure should be able
to fulfill an interface with a single method.

About the applicability, I'm under the same impression as you, the use case
is probably narrow, perhaps because anonymous classes is a newly added
feature and wasn't explored enough.

Cheers.
