Water heater hot water trapper - good idea?

[gawdyho]

Any reason NOT to install a hot water trapper on the OUTPUT of my water heater like below?

I recently had a dip tube break in my water heater and its clogging all my aerators. Seems to make more sense to prevent the stuff from getting there in the first place and ruining my appliances.

It’s better to filter the cold water inlet and flush the heater regularly rather than putting a trap on the output.
