This is a good idea in any case. But I don't think that activating or deactivating a thorn should change the output behaviour of another thorn - it is too unexpected.
Isn't that what would be introduced with the optional dependency on HDF5? One could see at this way: by default hdf5 is used, but there is also a fallback to ascii in case someone doesn't have hdf5 for whatever reason - so that the thorn is still usable. No parameter file would have to be changed for example. The simulation would still run.
Do people use the released version for production runs? I don't. But then, I also don't routinely update my main Cactus tree. There is little enough development going on in critical areas that this doesn't seem important.
Right. Therefore I think it would be ok to change the default behavior in the development version, as long as we don't forget to mention this in the release notes.
