I worked for several years at a world class company verifying CPU designs. Even into the late 2010s, designers were afraid to use basic features like structs because who knows what tool might not support it correctly. They emulated structures using piles of defines that set all the bit offsets. I wouldn't know how to begin to estimate the amount of senseless work that this led to during debugging. The lack of any type safety was appalling. If you were lucky, you could catch gross type confusion by having a linting tool notice a size mismatch. These tools found hundreds of real errors that should never have compiled in the first place. I could go on and on...
But there's no escaping it. There are so many amazing tools built around it. The vendors love the moat the complexity gives them. The IP developers have huge investments in legacy code bases. Compatibility is worth too much.
