this (and the other helper below) could be macros just fine.

They could, but they shouldn't.  Inlines are always preferable over
function-like macros.

says who ? And why ?

Documentation/CodingStyle

container_of() is type-safe, what is an inline function bringing as benefit ?

It's a general preference.  Because there's enough benefit to going
with inline functions and there's extra benefit to be gained from
having consistent style of code and documentation, as a general rule,
we prefer inline functions over macros.  If you have specific
technical arguments why macro is better, sure; otherwise, follow the
conventions for consistency if for nothing else.
