Windshear; "once in two lifetimes", but not knowing which life you are experiencing.

I’m questioning whether my thought process is flawed, and I’d like to hear how other 737 pilots think about this.
It is good professional practice to question our thoughts, our recollections, but don't forget that the safety objective must be to learn from 'experiences', not change many years of operations which could be included in manufacturers procedures.
If change is required - your justified opinion, then inform the regulator/manufacturer; who like us should note that the world is in constant change and not always for the better.
Change may be warranted, but who judges …?

A single event is limited to just one context, as might be the recollection of other people.
Procedures - rarely perfect, have to consider a wide range of situations; it is best to followed them at the time, don't outthink the situation because you may not have a complete understanding of the event - atmosphere or aircraft.
"once in two lifetimes", but not knowing which life you are experiencing.

Fig 1 in the event described below shows the range of airspeeds which might be encountered in a microburst, 110-150, and note that aircraft have a "robust construction", with certification margins.
