I think the thing that is missing is a simple way for end users on windows to replace blas/lapack libraries with MKL-a package that you install that puts the libraries in the right place.
Microsoft provides something for their distro, but we don't have the equivalent if you get R from cran.

With all due respect: You may miss something. MKL has always worked with 'Base R'.
As a point of reference and comparison, I set up a benchmarking and
comparison package _well over half a decade ago_ and while it never get fully
finished to the point of a submitted paper the vignette still stands---and
demonstrates that _dropping in MKL is a one-line operation_.
And always has been. There may have been some license arbitrage: Intel was
an early investor in Revo, so MKL was pushed hard. With GotoBLAS and later
OpenBLAS I cared less, but IIRC the license of MKL is a little simpler for
"mere use" now.
