Hey Jethro, so it sounds like you really cant hurt em.. I was thinking I can end up with warping and such.. like the cheap disk brakes and end up with vibration and crap..
ex.
years ago I had a '90 mustang on a CLOSED COURSE of course 
I took it up to some ridiculous speed like 135 and then hit the brakes a little to get it down to 100.. they not only did not work well but clearly didnt like it. I ended up with warp rotors that fast. 
I was thinking comparatively speaking with brakes that were once meant for 35mph, using them @ at 45-60 could also cause shuttering and such thereafter.
I did use them at about 50 and they seemed ok the one time I did it. <-- all that to say, I just dont want to wear the pads down or induce break wobble or shutter prematurely by continually using them @ 50-60 (mainly I would gear it down but... you know how people drive after 2019.. )
I will generally gear down anyway but sounds like they are pretty sturdy and consistent from your alls replies. I am also wondering how they do after down hill drives with a lot of needed braking. Probably same.. consistent but with fade I guess. Any and all replies welcome.
