 Replying to [comment:3 eschnett]:
 > I don't think that's worthwhile. This parameter doesn't influence
 correctness of the evolution, so let's keep things simple. 0 is already an
 unlikely value, most people would use 253 or so.

 OK.

 > If you want to propose a patch, then it should probably run in
 PARAMCHECK and use CCTK_ParameterQueryTimesSet. Please test
 checkpointing/recovery as well to ensure the warning works as intended.

 Cactus; this should therefore likely be a low-priority warning (maybe
 level 2).

 Now that I think about it more, this seems like feature which would be
 better suited as a part of Cactus. It happens quite often that parameters
 are deprecated, so having a standardised way of denoting this in the
 param.ccl would be better than implementing the code manually each time.
