I really do not understand how you can say this. On (very) old doors it
was not uncommon to find just a 4 or 5 point roller cam holding the door
closed with, if you were lucky, a short mortise bolt into the striker
plate.
Any good later door will have at least 3 mortise bolts which you will
certainly not be able to "pop open" without doing considerable damage.
Of course, if the frame has any movement in it or it is not properly
installed it is possible to flex the frame enough to get around some
mortise bolts.
This was why some manufacturers added a claw to the mortise bolt to
prevent levering out the bolts..

As someone who gets called out on occasions to help customers get in
after locking themselves out or losing their keys, I can assure you that
it is not an easy job to gain entry from the outside without doing a lot
of damage. I prefer to get a window open and take the door off from the
inside to minimise damage. If the door opens outwards it's very easy to
remove!
You only have to watch video of Police Officers using their Big Red Key
to see how well secured some PVCu doors can be. Others, of course, "pop
open" at the first touch.

Having good locks is a deterrent. A determined burglar will get in
regardless by snapping if possible but your average scroat will not
bother and look for another way in if he sees a good snap-resistant
cylinder.
The greatest advantage of the Avocet is that it leaves nothing for the
scroat to operate once they have snapped the front off unlike a lot of
other cylinders.
There are a lot of snap-resistant cylinders out there but if it doesn't
have a hardened steel centre bridge it can still be broken even when the
sacrificial section has snapped off.

I would upgrade to the Avocet if you have cheap cylinders installed. We
don't fit them ourselves, we fit Yale, but that's a cost decision by the
men in suits in our factory :o(
As for some of the other comments I have seen in this thread, no one
would even consider trying to pick or bump an Avocet cylinder. Drilling
really doesn't work very well either so you are left with snapping and I
covered that earlier.
