I'm not 100% sure whether the result of the changes in this PR is correct, could you double-check whether it's correct? After that, I'll add some tests

@ueman we'd like to do the exception grouping in the v9 branch, do you wanna continue this? if not I can take over

[ueman]

Feel free to take this over. I guess the idea should be clear and it's just a matter of executing it

[buenaflor]

closing this then and will continue on the v9 branch
