As a user, when i'm viewing a period where the "average generation time" is zero, for example under "Visitors > Overview", it would be helpful if:
Context: currently this metric is shown for Matomo instances that used to track this metric (before Matomo 4). Which is helpful, but in this issue we just want to remove any confusion and hide the feature when it's definitely zero for the selected period.
Otherwise if it's a bit too complex, instead of implementing the "smart" remove, we could just remove this metric completely, once we have implemented the new metric in #17013 - this would be good enough as people will be able to use the new metric now. (and would still be able to access the old metric in API)
Do I understand it correctly that the old metric will then not be available for comparison in the UI anymore? Our non-dev users have to pull the raw data from the API? 👀
