read 30 mins of the sand rinse thread and click the work examples. message the entrants in the thread for statements on outcomes, then compare that to the info you're being presented here let me know which you find to be reliable. a third reason we pre rinse comes from the section in post #1 of the sand rinse thread where rock slides or powerheads dislodged, and re clouded the tank and irritated corals for days, its specifically in the links provided and specifically excluded here by the umpires as potential issue.
as you can see, there's no benefit to keeping the sandbed in this state, there's total benefit in you prepping it correctly. you have your posts with links, and posts without any links now or in the next five pages, choose where you think the proof exists. good luck on the new nano.

*your sand has about an 80% chance or better of self clearing, the harm you incur from the bad advice is the early seed of bacterial doubt, you cannot imagine how much trouble that causes in reefing. Just yesterday, Elora was advising an owner of a completely cycled reef tank that he may not be cycled, and needs to redose ammonia again, preventing this reefer from beginning though his tank was weeks old and had used instant-cycle bottle bac on day one. We'd already proven closure, and the conflicting info simply sets reefers back a mile or two in their system control abilities. too busy doubting
in this thread you have implied and stated consequence from rinsing sand, yet in the 6th year running collection of sand removal/rinse tanks above, you see only perfect outcomes. That's the difference between making up stuff and earning input by actually doing work and logging it.
