True. While I think Retina is fantastic for soft proofing photos, I'm not sure I would even go for it otherwise. I guess MacOS also has to contend with resolution scaling/gain issue if you're using multiple displays, and maybe that is an issue mainly for people using iMacs. When I use a laptop I generally don't care about mismatched ppi since I usually set up the displays for different things or ignore the laptop display altogether outside of outlook/teams...
On a new machine, I'd be tempted to go for a dual 4K set-up but up the screen size to a 30-32" range, desk permitting. My eyes ain't what they used to be.
