I suppose if you're using them at the top of a wall where there is little
weight on the bricks this might happen - but it happens with plastic plugs
too. They both rely on expansion to grip. The difference being the bolt
type can exert more pressure. But that's in the hands of the installer.

and With a predrilled
template like a steel tv bracket you often need the holes exactly
positioned and have no way of knowing what part of the wall fabric you're
hitting until you drill. That's when it might be time to use a 'decent'
wall plug (like the basin hanging variety) and some Rawlchem (or other
polyester resin/2 part).

Exactly the same applies to any fixing which relies on expansion to grip.
A resin type being different. However, a suitable sized bolt type will
work in a mortar coarse - unlike a plastic one - due to the greater
possible expansion.

As I mentioned... It depends on wall- at the point you are drilling. Go
for the anchor bolts but have the other method on standby for
disintegrated holes.

Overkill doesn't worry me.

As long as it works

The only possible disadvantage with bolts is they cost a lot more. Which
simply doesn't matter in this case. It might if you're throwing things up
for a living - like satellite dishes - where the profit margin can be
small.
