Fully agree.

It would be true if C-x e or C-x e e e,
but not if M-2 C-x e or C-u C-x e.

I agree, so in the current example, interactive-p actually does the
right thing IMO. So as there is no clear idea of what is "correct",
checking anything seems futile.

Actually, you can't!!!
I tried to make a quick fix for this, but the "This is a message"
still doesn't appear... because there is an explicit check in the C
code for `message':
if (INTERACTIVE)
{
... output message in echo area ...
}
where the definition of INTERACTIVE closely matches that of
interactive-p:
/* Nonzero if input is coming from the keyboard */
#define INTERACTIVE (NILP (Vexecuting_macro) && !noninteractive)
So no matter whether we use interactive-p in the current or new
form, it cannot be used to determine whether message should
print in the echo area during macro execution -- message doesn't
print in that case!
So what's the point in the whole discussion ?
