In my opinion it would be better to let the user to define a ttl value for his/her own samples. I do not see the use case, where it is needed to delete samples, also if the user is able to randomly delete some data, then the statistics functions will not generate a valid output for that data set, which was affected by the deletion. As the original question was about testing, I do not have a deeper knowledge about how testing works now regarding to generating and storing the samples. Maybe if there is a need for deleting data there, it can be considered that how we can handle that particular case.
How would we identify the samples, which should be deleted? If it is allowed to delete any samples from the system via the API, it does not sound good either. So if it is an all or nothing situation, I would say nothing.
