We should check if and what might be different in the generated bundle. Although in theory nothing should change?

[danez]

Maybe we should also turn of the codecov PR comments, they get really annoying:

• It posts multiple times recently
• The information is not useful and also available in the PR checks

[hzoo]

Yeah I basically ignore them now..
