The Exception "exclusion solution" definitely it's not personalized and Sourcehut-only but available to anyone that requests it and in the issue track you can see several people that are using this exclusion already.
True that an opt-out (what this solution boils down to) is not ideal but it's way better than using your users quality of service to try strong-arming your side. And anyway from the go team it's been made clear that they are working on improving the situation of the refreshes and this opt-out is just the temporary solution until they fix the real issue.
