Extension of data format to allow for lists of simulationConditions and timepoints
To be discussed at a later point
Sounds to me like something that could (theoretically) be handled by an event in some way... We have not really talked about how to implement events in PEtab beyond waht's supported in SBML: Another such point would be event observables...

Definitely.
I would find it nice, though, if the model would focus on the biology, and any weird experimental setups used to generate training data could be kept out of there. The model would have include the superset of all events, which could get messy if you have a number of different setups. (Alternatively you could build a different model for each of those, but that's no fun either).
Also it would be a nice feature if we want to support non-SBML models in the future, that don't come with anything like events (#436).
