So if you want to make it a "greaser" then you have to "float down the runway" ?
If that is the argument, then why not aim for the 500' markers, float for 500' and "grease it on" at the 1000' markers ? surely this meets ALL requirements ?
Personally, my approach is to touch down on the 1000' markers AND try to grease it on. works most of the time, provided one remembers that Vref is the speed at which one should cross the threshold at 50' AGL, and not a touchdown speed!
