I have run into these same issues, it's particularly frustrating once you see a Reddit thread from a couple years ago outlining the exact issue. For a large consumer-focused company like Apple this can only be explained by ignorance.

From a developer perspective many of these inconsistencies are rooting from inconsistent access patterns - operating system (ABI?), applications (ICP?), remote (TCP, HTTP, LDAP, FTP, ...?). All of these are "execution" or "information" but have to be programmed against differently.
