HDF5 Filters only Required when Writing Data

There is a class of HDF5 filters which are only needed when storing chunk data in a file. Should such filters be part of libhdf5 or exist as dynamically loaded plugins? If the latter, is there currently a way to indicate that a filter is not required when reading chunks?
