This is one of the things that I feel is an inappropriate abstraction that is around for historical reasons. When I do FFI to call C from rust, I usually wrap the generated API (Which is pointer based) into rust's &[] array syntax. Arrays/lists/Vecs etc in most non-C languages feel like an abstraction over a collection of items; I feel like C's exposing the pointer directly is taking a low-level memory/MMIO operation and inserting it into business logic. Conceptually, I like to keep them separate; pointers for writing drivers, accessing registers, writing to flash memory etc. Arrays/lists/vecs for higher level operations on collections.

Tangent: I have a pet theory that part of Zig's raison d'etre is to fix some of the problems with C, while accommodating its pointer-based data structures, and the resulting patterns.
