I think this depends a lot on whether you're already using high level languages and lots of external libraries vs doing lower level programming using something like C/C++. I managed a large dev team in a Microsoft shop and it would never have occurred to anyone to ever create their own compiler. Even the most experienced programmers would have just continued to brute force things atop .Net's compiler until it eventually "worked". The result, combined with esoteric and poorly understood business requirements, was fragile spaghetti code few could parse for bugs or updates, but it was still several layers above the compiler.

This attitude is by far the most common among "enterprise developers", and one of the big differences between people building things from preexisting building blocks vs -- as witnessed from my 8 years at Google later -- people who think they're smart enough to build everything from the ground up, and do so, using primitive blocks and custom compilers created by similarly hubristic engineers who came before them.

Ymmv, but this has been my experience over the past 25 years.
