Looks good to me.

Actually, with this, couldn't we just disable isig while inserting the
characters?

If the terminal ensures that the end sequence is filtered in a bracketed
paste, the shell can also be sure that anything inbetween is not user input.

I guess we can't use terminfo has no feature for this, right?

emacs disables the transient selection when pasting (which is inserted
on the current cursor position). For vi I'm not sure what I would
like... maybe the same. You have to enter insert mode normally, so it
would make it identical in behavior. Maybe gvim is different?
