But the main point is that there is a context. For instance,
a context can be:
echo http://localhost/foo
or
echo 'http://localhost/foo
If I type "?", I expect "\?" to be entered in the first context,
and "?" in the second case. Ditto if "?" is pasted. In both cases,
the action remains inside the unit. So, I don't understand why
bracketed-paste-magic doesn't behave that way by default.

bracketed-paste-url-magic is something new to me. I currently have:
autoload -Uz url-quote-magic
zle -N self-insert url-quote-magic
autoload -Uz bracketed-paste-magic
zle -N bracketed-paste bracketed-paste-magic
zstyle :bracketed-paste-magic paste-init backward-extend-paste
the only reason of the zstyle line being to get the above expected
behavior when pasting "?". Do you mean that instead of the zstyle
line, bracketed-paste-url-magic would do the work? Does this replace
bracketed-paste-magic or should bracketed-paste-url-magic be used
in addition to bracketed-paste-magic?
bracketed-paste-url-magic is not described in the zsh man pages.

I would say: the same behavior as url-quote-magic.
URL's normally don't have quotes. For instance, when searching for
"foo"
or
'foo'
(with quotes) on Google, Firefox displays the URL's with quotes,
but when I copy-paste these URL's to Emacs, I get:
https://www.google.fr/#q=%22foo%22
https://www.google.fr/#q=%27foo%27
and I assume that's Firefox that escapes the quote characters (there
may be a RFC requirement concerning allowed characters in URL's, but
I haven't checked). Note that such escaping is not just useful for
shells, but also for pasting URL's to an XML document in an editor,
since XML attributes also use " and ' quote characters as delimiters.
So, I think that a quote should have its usual shell meaning like
with url-quote-magic (though this could also be configurable).
