update_cookies in client_reqrep.py has the same performance issue that was solved for the jar itself in #9204

The cookies get recreated every time. I need to dig into the cookie code some more to see if we can avoid this

aiohttp/aiohttp/client_reqrep.py

Line 510 in d74e51b

if isinstance(value, Morsel):

I think we have to wait for python/cpython#126157

[bdraco]

If we don't find another solution by the time Python 3.14 is released, we can close this one

I think its unlikely we are going to be able to improve the performance without moving away from stdlib http.cookies. As the change to improve Morsel creation time is already merged upstream, I think there is nothing left to do but wait so I'm going to close this issue out.
