The code paths where bpf hooks are placed are very performance
sensitive.  If macro is used, users who want to customize their own
binary can change those hooks inline.  If expanded, they have to
manage bigger local diffs, which is not good for serious 3rd party
users.

(There surely exist such users.  At least @ a company at Jimbo-cho.
The problem is they don't speak.)
