Actually 404 *is* an application level protocol response.
"The Hypertext Transfer Protocol (HTTP) is an application-level
protocol for distributed, collaborative, hypermedia information
-- from RFC2616
That's why I mentioned the server to browser part. That part must say
"what you gave me was invalid", that's what 404 is for. Otherwise my
'absurd' search engine scenario *will* (and does) happen.
But, you can of source present something nicer to the user.

That only holds if an "archive" with our without posts is something
WordPress considers content. It very clearly does not, and nothing in
it's history or future indicates it will.
And we are still back to the idea that every possible "archive" becomes valid.
Even if you restrict it to "date of earliest post until now" that is
still a lot of 'valid' URLs with no content.
This blog, (which used to be WordPress) http://www.pepysdiary.com/
would have over 124,000 such empty URI's (127,000 possible days,
versus 3285 maximum diary entries)

It's not a viewpoint it's a fact based on exactly what the code does
at this moment in time.

As I mentioned there *is* an easy way to divert the standard 404
response and present a different one.
