Yes, it does.
The standard requires a diagnostic message for certain errors, and
defines a "diagnostic message" as "a message belonging to an
implementation-defined subset of the implementation’s output messages".
The phrase "implementation-defined" means the documentation has to
document it.
gcc's documentation, for example, says:
* 'How a diagnostic is identified (C90 3.7, C99 and C11 3.10, C90,
C99 and C11 5.1.1.3).'
Diagnostics consist of all the output sent to stderr by GCC.
That's for C, but the "C++ Implementation-Defined Behavior" says "Some
choices are documented in the corresponding document for the C
language."
So no, for gcc/g++ not blinking the caps lock is not a diagnostic.

I prefer to assume that *the standard means what it says* whenever
possible.
In this particular case, I think that the wording of the current
standard, though it's unambiguous, has an unintended consequence.
