Well, you can't write malloc in conforming C, which hurts rather more than remembering to write bitcast as memcpy on char pointers.

Doesn't matter though because you aren't writing standards conforming C. You're writing whatever dialect your compilers support, and that's probably (module bugs) much better behaved than the spec suggests.

Or you're writing C++ and way more exposed to the adversarial-and-benevolent compiler experience.

The type aliasing rules are the only ones that routinely cause me much annoyance in C and there's always a workaround, whether if it's the launder intrinsic used to implement C++, the may_alias attribute or in extremis dropping into asm. So they're a nuisance not a blocker.
