This doesn't seem like a good idea to me.

If we add a custom option, doesn't that constitute a promise that the 
curly quote translation *will* work for at least several releases of 
Emacs after that?

Because the option would have a value meaning "translate straight quotes 
to curlies", and we'll have to support it once the option is introduced.

I would too (though I wouldn't actually mind it if it were implemented 
in a very different fashion). But this is a totally different direction 
from "let's add a user option". I think.

Can we actually leave it in, while all but promising to take it out in 
the next release?

That would seem like an odd choice.

As a member of a somewhat younger generation, I can say that they look 
fine in Help buffers, manuals, and so on, although they do not look 
"modern". The curly single quotes feel more like certain tech in 
alternative history novels: shiny, could be considered cool in some very 
specific circles, but nobody uses anything like that in the modern times.

I never want to see them in my source code, though, and the benefits, 
whatever they are, do not justify the increased complexity in the 
associated facilities.

The problem with using the "don't translate at all" option is that it 
allows you to write code that won't work for other users.

For instance, if we had such an option now, Alan wouldn't have found the 
presently discussed bug. It wouldn't not manifest with his setup, but it 
would manifest in default Emacs configuration where quote translation is 
enabled, and the majority of the users would suffer.

For that reason only, I'm against having an option like that.
