It is up to the operator if they want to add things like brakes off to pre-landing checks. It's quite another to ignore the POH and just lazy to adopt a one size fits all instead of reading the POH for different types.
POH for Tomahawk and Warrior state in section 4:
APPROACH AND ANDING
Carburetor heat should not be applied unless there is an indication of carburettor icing, since the use of carburetor heat causes a reduction in power which may be critical in case of a go-around. Full throttle operation with carburettor heat on can cause detonation.
Section 4 of POH for C152 states:
BEFORE LANDING
1. Seats, Belts, Harnesses -- ADJUST and LOCK.
2. Mixture -- RICH.
3. Carburetor Heat -- ON (apply full heat before reducing power).
AFTER LANDING
1. Wing Flaps -- UP.
2. Carburetor Heat -- COLD.
BALKED LANDING
1. Throttle -- FULL OPEN.
2. Carburetor Heat - COLD.
3. Wing Flaps -- RETRACT to 20°.
4. Airspeed -- 55 KIAS.
5. Wing Flaps -- RETRACT (slowly).
So, similar to the "in case of a go-around" reasoning that people give for opening cowl flaps on final, where for example C182 POH says to open them for a baulked landing; it shows that people are just parroting rather than learning.
