The message
from (BridgeP) contains these words:

I don't want to denigrate Old Bob in any way, but because a
professional does
it a particular way does make it the right way. Of course, many new bricks
don't have frogs at all, just holes.

However, if two professionals do it two different ways that doesn't
necessarily make them both right, or both wrong, nor either one.

Getting back on-topic, those holy bricks can have their spaces filled
with peat etc and planted with succulents - house leeks, stonecrop etc,
and arranged about the place, used as doorstops, etc.
