My only argument against it is that it makes the code more complicated to maintain
from blockarrays.jl.

Perhaps it would make sense to have BlockDiagonalMatrix <: AbstactBlockMatrix, as such a structure is often known a-priori. Special methods may then be added for such a matrix type. I imagine it'll be some work to resolve method ambiguities, so perhaps this can be attempted in a separate package, and once it is stable, it may be merged with BlockArrays. In this approach, BlockArray methods don't need to infer matrix structure, so this won't complicate dispatch.

There are already two packages for this:
