You're not wrong but that's more of an issue with C than an issue with intrinsics, in higher level languages like C++ or Rust you have the option to wrap instrinsics in types which are much nicer to work with.
Not just an eyesore, they also are typed, so any widening or narrowing or using only part of a vector register ends up needing casts so things can get really extremely confusing and cluttered when doing anything beyond basic algebra. With asm it's a much shorter, more elegant and visually-aligned waterfall of code.
