But, yes, I think that when using private_data the restoration is

This is one of the reasons not to use private_data at all.
Would it be safer and easier to maintain if this was instead done within
call_dissector() and friends?
Probably but I've always had this belief that TRY/CATCH stuff was
expensive so I try not to put them in (and have, in several cases, taken
them out when they were clearly not necessary). Unfortunately I don't
remember why I think they are expensive...
