is what it is called.

HLL or not, the issue is "abstraction"

You "can" make a '51 work with a RTOS, malloc(), function pointers and no knowledge whatsoever of the underlying architecture.

I have seen that in a product that "worked beautifully, but had a small timing problem"

The above with 256k of code banked memory, the fastest '51 available at that time ended up with using ~41k of code memory and NO timing problems when the "abstraction" was replaced by "realism".

YES, the above would have worked a year later when a faster '51 came out, but it would still be the equivalent of 5 splatters of paint on a canvas compared to a Rembrandt. If you are so inclined you can call both "art".
