I wish the external Mac keyboard had grouped function keys. I wish I didn't have to use an external keyboard in the first place, but touchbar is even worse. In my case debugging stuff becomes annoying with ungrouped keys because it's easy to mix up step into / step over / continue.

You're excluding pretty much every laptop there.

I don't find laptop keyboards reasonable. They are a last resort.

Thinkpads group their function keys. Who outside apple doesn't?

Thinkpads also have nice keyboards, so are hardly representative of laptops in general.

And in line with the other commenters, my corporate HP and Dell laptop function keys aren't grouped. Fortunately, I interact with both through a nice external keyboard.

My HP laptops don't. It's been ages since I used a non laptop keyboard and I forgot about grouping. It's a useful UX though.

Dell.
