Doing this tends to prolong the life of the steering fluid pump, which is more labor intensive and pricier to replace.

Eh, my car has 382,000 miles on it with the original PS pump and steering rack. I've drained and replaced the PS fluid twice, at 150K and 300K. The only thing I've done to the PS reservoir is replaced the o-ring on the cap, which prevents the fuzzy oil gunk every BMW with that reservoir gets. I've never seen any manufacturer include PS fluid as a routine maintenance item.
How do you know it becomes somewhat eventually clogged? Have you tested one, or opened an old reservoir up and inspected the filter? I think the filter getting clogged is just an assumption. Have you ever replaced the lifetime fuel filter in the fuel tank?
