People don't need to propose new solutions to fix how Larian has done passive perception. 5e already does so, and does so better than what we currently have. Passive perception isn't a roll.

It's one of the big reasons to have a rogue go first, when they have expertise, they have a very high passive perception, and so can spot all of the dangerous traps.
