You would stop all WiFi experimentation just to decrease slightly the odds of inference with a radar that _might_ help prevent a crash? We don't live in a society focused entirely on safety. Safety is important, but it's not trump card that automatically beats all other concerns. When a proposed policy reduces risks only slightly but has large costs, we shouldn't enact that policy.

Now, who decides what "slightly" and "large" mean in this context? You didn't provide any numbers. Given that 87,000 [1] flights take off and land safely in the US each day and that there have been 20 reported TDWR inference incidents ever, we cannot justify the harm this policy would do to the technology community.

This is just a variation on the old "Turn off your Game Boys before takeoff, or the plane might crash" schtick.

The proper way to fix that issue, if there ever was one, was to mandate the implementation of avionics that can't be jammed by a Part 15 device. Instead, look what happened... we got a decade of silly, groundless rules that had no useful effect and were eventually scrapped.

Now it looks like it's the WiFi industry's turn. Gee, maybe putting weather radar right next to an unlicensed ISM band wasn't such a great idea. Maybe they're the ones who should move.
