I'll also disagree on the "everything is bytes and we slap an encoding on it some of the time"... But add there:

- User level security, instead of app level or task level, or whatever.

- Aged IPC primitives that assume too much to the point that modern hardware has to be built around it (and slower because of that).

- Added later, non-core network support, leading to bad integration.

- Added later, non-core, or sometimes never added encryption support, leading to bad integration.
