Just want to note that this is type-piracy by SuiteSparse, and might make it more difficult to decouple SuiteSparse, SparseArrays them in the future.

We should flesh out the possible dependency graphs between SparseArrays, SuiteSparse, and the (currently non-existing) SparseLinearAlgebra packages and discuss benefits and complications.

While it's true that this PR might add to the confusion, I suspect it won't add much work to the eventual decoupling process. A solution could also be to just define this method in the current linearalgebra.jl in SparseArrays and make it call qr anyway. It will then just fail if no sparse QR is available.

The question around separating SparseArrays and SuiteSparse is whether Dense will also roughly split the same functionality into separate packages. Otherwise, we will end up with a real patchwork of what sparse capability lives where and will be different than dense.

Is this ok to backport, at least to 1.1?
