Would be pretty fun doing stealth speedruns for heists that actually support stealth as an alternative approach. It being as a third category next to any% and botless would be nice.

Example rule: You cannot trigger the alarm (not even escape alarm like in Shadow Raid which gives you 1 min to escape)

Just my two cents, but I don't think it's necessary considering stealth is already faster than loud in almost all hybrid heists, so it would be redundant with any% boards. And there is also a huge majority of heists that can only be played in loud.

Personally, I like this idea, but it would have to be worded so that an alarm can't be triggered during the entire run. (With the exception of Car Shop obviously) I do see what you're saying for general, but heists like Bank Heist would technically have two categories to be ran then since the current record doesn't play into stealth.
