The Compressor is more or less the state of the art in compacting compressor GCs. It would be excellent to have an implementation in MMTk.

Be aware that the current implementation has some assumptions about the runtime. And it does not work for runtimes that cannot satisfy the assumptions. See https://github.com/mmtk/mmtk-core/pull/1340#issuecomment-3101148872 and https://github.com/mmtk/mmtk-core/issues/1353.
