Sorry, back to the thread.

If we hardcode 1 value, why not hardcode the 2 other:

@defvar emacs-major-version
The major version number of Emacs, as an integer.  For Emacs version
26.1, the value is 26.
@end defvar

@defvar emacs-minor-version
The minor version number of Emacs, as an integer.  For Emacs version
26.1, the value is 1.
@end defvar

That's an even better illustration of the variables and it costs extremely little since we already hardcode the value of (emacs-version).
