So here is a new request created from bug#50881.

So does this mean that if someone has previously
turned on `show-paren-mode' (globally) s?he now has
to explicitly turn it on in `special-mode'?

If so, why impose that backward-incompatible change?

Sorry, but I object to turning show-paren-mode off just 5 min after we
turned it on.  Please wait for a month at least before reporting
problems with that setting that are not clear bugs.

If you read a book where every paren is emphasized,
what would you think about the author?

If I read that book in a reader app, I'd look to
see if that was a visualization option - but only
if I didn't find it useful.

We cater to users.  We give them optional behaviors.
Some such we turn on by default.  Some users don't
like the default behaviors, so they customize.

Nothing new.

We saw similar arguments back when the choice was
made to turn on `font-lock-mode' globally by default.
Until that momentous decision it was off.  Imagine
the consternation of the multitudes who suddenly
found it on.  They survived, and so did Emacs.

The question is whether emphasizing the parens at the
first line of 'C-h C-h' was an intentional change or not.
If not, then it's a bug.

It doesn't matter what I think.  If I don't like that, I can turn it
off.

Moreover, some special modes display code fragments, where
show-paren-mode is definitely useful, especially to newbies who don't
yet have parenthesis peeling off burnt into their brains.  Even *Help*
buffers show code fragments.

Please, just let this feature alone for a while.  Disable it in your
customizations if you cannot stand it.  We can come back to it later,
when we have enough experience collected from those who will see this
default for the first time when Emacs 28.1 is released.  They are
those for whom we made this change, so let's hear their opinions
before changing anything.  My personal experience suggests that at
least some of them will have no problems where you see them.

The intent is to emphasize parens _everywhere_.  That's what the
feature does, and that's what we intended to turn on by default, and
asked users to provide feedback about.

So I've now done this in Emacs 29.
