Do you mean that the new mechanism would not be able to do
the same thing here?

Preservation of array subclasses in linalg functions is not very
uniform, and will likely need fixes in several of the functions.
Since new code in any case would need to be written, I'd prefer
using the "new" approach and so leaving us the option of marking
the "old" approach deprecated.
