Very improper and totally bad approach. This is for sure not the right
direction for further usage of management operators.

classes with auto free has a lot of sense (without modifying classes design
related to usage of heap), anyway old modes should stay untouched, and the
new feature should have no negative influence on performance for RTL and
Object Pascal. Because of legacy of all FPC modes the topic is a little
complicated but IMO is possible to achieve (for such feature new mode
should be introduced [and maybe modeswitch]).
