Try sitting where you can see the threshold and watch people land, you will see many flare and land instantly, nearly all putting all three wheels on at once or even nosewheel first, it is surprising how few actually land properly on the mains with the nosewheel held off.

This has a lot to do with the distance between the nose wheel and mains short coupled and a larger degree pitch up is required to move the nose wheel clear.
longer coupled like the citation and probably only a couple of degrees change is required but even singles like the Saratoga have a decent distance between the nose wheel and mains.
Looking at passenger jets and the distance is obviously huge while some tiny aircraft have hardly any spacing between the two and are not really bad weather aircraft.
The above comments you placed shows how many cannot really land properly and you have to question the instruction and many do sit there in crosswinds holding off at 10 feet
