None of what I wrote has anything to do with this.

No, deprecated means that a feature or practice is considered
dated in favor of something else, and that one should avoid using
it, where possible. It is by no means a strict mandate that you
must never use the feature. (Although, you obviously can't use the
feature whenever you move to the new version in which a deprecated
feature is dropped.)

No one, but I never wrote or implied anything like that.

It's not a big deal. If you're writing new code, today, there's no
reason not to avoid using the mysql extension. That's all. I'm not
warning to toss away or fix old code *right now*.

And, if anything, it's myopic thinking to write code depending on
a deprecated extension in situations where you don't need to.

This is a ridiculous straw man.

What do you mean? What do you think trying to inform people about
best practices is all about? No one here is imposing mandates on
anyone. We can just offer the best advice as we're able, and it's
up to the OP and others who might read the advice to do with it
what they will.

No one has written this. When I read Thomas's post upthread, for
example, it read as a helpful aside to me. It was quite clear and
concise. There's nothing vague about informing people about a
deprecated feature.

Again, no one has written that people's code will break overnight.

Usenet is not my job; Usenet contributors don't get paid for
posting. I generally post here in the event that I feel I'm able
to provide what little help I can. Further, newsgroups like this
have been a big help to me, so contributing back is a nice change
of pace.

> NOT making gregarious claims

I've never heard claims described as gregarious. Perhaps you meant
grandiose? If that's the case, I made none.

The mysql extension is deprecated, but this has nothing to do with
magically breaking Web servers. It's a simple warning to
developers (and sever admins), that, at some point, the extension
will be phased out.

It's a helpful warning and is intended to give people time to
prepare however they choose. For some people, the concern probably
isn't immediate. That's fine. However, there's absolutely nothing
wrong with suggesting to beginners that they ought to use instead
mysqli or the PDO MySQL driver.

There are other reasons for using alternatives to the mysql
extension that go beyond the fact that it's deprecated (although,
they likely have contributed to the fact that it has become
deprecated). For example, the fact that you can use prepared
statements or, in PDO's case, it provides an abstract interface to
allow developers to reuse code for multiple databases.

I have written it in the post you quoted. Although, I didn't write
in all-caps, so perhaps you missed it.
