[KTL]

I think you mean never use the transmission for engine braking? Agreed, brakes are much easier and cheaper to service than clutch/transmissions and/or engine rebuild.

To further awhnry's point, I think its a waste of coordination and clutch operation to sequentially change down gears under braking. For example, going from a long straight to a slow corner I go right from 5th to 2nd at the end of the braking zone instead of going 5-4-3-2. Easier to match revs/heel-toe at lower rpms as well, IMO.
