AFAIK, ISOLatin1AccentFilter was deprecated because ASCIIFoldingFilter provides a superset of it mappings.
I haven't done any benchmarking, but I'm pretty sure that ASCIIFoldingFilter can achieve a significantly higher throughput rate than MappingCharFilter, and given that, it probably makes sense to keep both, to allow people to make the choice about the tradeoff between the flexibility provided by the human-readable (and editable) mapping file and the speed provided by ASCIIFoldingFilter.
