It is entirely possible, but is not trivial, especially for the user who then needs to know "arcane knowledge" of BLAS/LAPACK work array sizes and flags. There was some discussion about this on github, but it sort of trailed off without a real resolution. I think it is considered too complicated/niche to be in base, and was recommended to be an external library, but nobody (myself included) seems particularly interested in what amounts to maintaining a fork of the entire BLAS package. The base devs would have more insight, but this is my view from the outside at least.
