What plugin would have a need for it?  Freeing the protocol tree filled up by a dissection done elsewhere would be considered a bit impolite, as it might pull the tree out from under somebody using it.  If the plugin has done its own top-level dissection (which seems a bit odd - dissectors shouldn't be doing that, taps shouldn't need to do that as the tapping should be doing the dissection for it, file format plugins are at a level below libwireshark and shouldn't even know what a protocol tree *is*, and codecs are orthogonal to dissection), it should have done it with the epan_ APIs and thus should free it with a call to epan_dissect_cleanup() or epan_dissect_free().
