In the thread for bug#4287 I proposed adding an after-load-hook hook
to `load' (obviously :-).
Stefan said:

The following patch adds `after-load-hook'.
Comments:
- It is not `after-load-functions', because it is a normal hook
(though `load-file-name' is set when the hook runs).
- I haven't touched do-after-load-evaluation because I don't
understand what Stefan means by "replace" in this case.
- No NEWS or info yet.
