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.

See  https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf  for more.
