They are used in mir-lapack [5]. The bug fix also required for
mir (Sparse, CompressedTensor), and for the future Dlang image

I was experimenting with one of the open methods matrix examples
[1] and trying to replace the virtual methods with templates. My
example [3] does it statically and with structs so that it could
be used with mir. However, the moment you try to make it a little
bit more complicated and allow the type of the underlying matrix
data to be templated, then it hits up against this issue and you
can't rely on aliases any more.
I would support a DIP.
