Description
Currently, one needs to split matrix multiplication into products over the components to avoid hitting generic fallback functions. Would it make sense to implement various matrix-multiplication methods for StructArray{<:Complex} types in this package as a convenience?
I realize that this risks becoming a minefield of ambiguities, so it'll require significant effort to disambiguate with all the structured matrix types defined in Base. It'll also mean that we'll have to add LinearAlgebra as a direct dependency.

Research direction
Start by tracing the generic fallback paths reached by matrix multiplication for StructArray{<:Complex} types, then review the structured matrix types defined in Julia Base. Assess the ambiguities between those types and the implications of adding LinearAlgebra as a direct dependency. Done means a documented scope and implementation plan, or a supported implementation with coverage for the relevant multiplication methods.
