Point taken, umbrellas solve real problems.
That I completely agree with, and that’s exactly the reason I stopped keeping records of my argumentation for or against X or Y; I trust my judgement and experience and if that means some semi-irrational bias here and there then that’s a deal I am willing to take because it saves me a lot of brain energy. But yeah, I can accept that in this case the bias might be unjustified. Open to hear arguments in the other direction – and you provided them. Thanks.
Maybe it’s worth I dug into the very limited set of former work code that I was allowed to keep by contract and for self-educational purposes only and see if I can remind myself why I hated umbrellas so much at one point.
