A huge difference is that you may very well get 20-30 requests in a
row to the same service.
I think using GSS without associations is incredibly impractical.

It is not always possible to detect.
My argument is roughly that you need to have some mechanism to put the
selector into always-reconfirm mode that is well understood. Nothing
we're talking about here seems to avoid that requirement. Once you have
something that your users understand to put things into a mode where it
is always reconfirming associations, it seems that you can be more
aggressive about making the associations.
I'll note that we have currently seen no proposals to convey a good UI
for enabling the always reconfirm mode. I'd be very interested in a
credible approach that didn't need that. However, while we've had
proposals for reducing the number of erronious associations, none that
get it low enough that I think it will be usable without the average
user understanding how to trigger such a mode.
