Research direction

Start with the linked Discourse discussion and inspect the existing trait and array-operation interfaces in ArrayInterface.jl. Determine whether reduce and broadcasting can be routed through traits, with done defined as efficient BlockArrays support without requiring an AbstractBlockArray subtype.

Written by the indexing model from the issue text.

Description

In light of this discourse discussion, could we also support BlockArrays in ArrayInterface.jl? I have time weekend after next to take a stab at implementing the suggested changes in that post.

Ideally, make efficient BlockArrays possible through traits, rather than having to subtype a AbstractBlockArray. Note, that I'm not familiar with the details here at all. Rerouting reduce operations, broadcasting, etc. through some set of traits might already be basically implemented or trivially easy to add. Or it might not even make sense.
