It’s somewhat bizarre to me that the settings menu isn’t just a reskinned control panel that either launches the new or old items depending on what they’ve finished so far.
I can’t imagine what they’ve done is easier than rewriting control panel items in full one by one.
You can do a halfway decent job of modernizing just by having an “advanced” toggle that shows the more arcane/less used settings.
I understand the desire to race towards a minimum viable product and get the core functionality into the glossy new thing, but they already had a minimum viable product in the control panel.
I usually rinse them. The spines relax enough when wet.
Alternatively there’s the golden kiwis which have skin that remind me of pears, just thicker. They don’t have spines. I’d still to prefer to rinse them, but more because you should rinse fruits and veggies if you’re going to eat the skin.
