I've never tried that. Do ec.revert() and deleteObject() still
function correctly?

Sometimes it may be better to just disable registrering undo
notifications in undoManager with:
editingContext.undoManager().disableUndoRegistration()
If you don't use undo's in your app then you can do this for all
editingContexts just after their creation.
There is a method to set levels of undo which undo manager remembers
(setLevelsOfUndo) but be aware because 0 means 'no limit' and this is
default value.

Deleting needs an undo manager. Better is to add
ec.undoManager().removeAllActions() after (successful) calls to
saveChanges(). This lets the EC continue to function and avoids
carrying needless baggage (pre saved state) around.
try {
ec.saveChanges();
ec.undoManager().removeAllActions();
}
catch...

To quote Dory, "LIttle red light going off".....I think there is a
problem with setting that to null, or it already is, or it resets it
to the default manager regardless. I believe what we did or
considered, was mocking up a dummy undo manager.
But....I could be way off base here....it is thursday after all.

Perhaps
you can add : setUndoManager(null) on your editingContext.
If the application doesn't need undo at all, you can avoid any undo
overhead by setting the editing context's undo manager to null with
setUndoManager.
Have a look at :

Hope this help
