This has been a substantially limiting factor on adoption of the standard -- it's historically been hard to find mainstream compute scenarios where MRAM offered an acceptable alternative to SRAM when it comes to CPU caches, even though it has other theoretical density and power consumption advantages that could make it a good fit for these markets.
The historic problem with attempting to build large arrays of hundreds or thousands of CPU cores on a single die is that even very small CPU caches drive up power consumption and die size very quickly.
