My port also got wallered out but it's a very easy swap. 2 case screws, pop off the back, undo 2 more screws to remove the USB/audio jack assrmbly and swap in the new one. No glue, no kamikaze springs, no muss, no fuss.
Its a $5(ish) part plus shipping from iFixIt, and took me 20 minutes. I replaced the battery too, sonce I was already in there with the back off. Also an easy swap.
If you're one of the lucky few who lives where it's sold officially. Pixel phones have a notorious QC issue there's no way in hell I'm going to get one without warranty.
I used my Oneplus 6 for about that long and moved to lineagos after updates stopped before retiring last year. Phones are getting more powerful while the app demands aren't really increasing, so I think 7 years isn't that outlandish now days.
There's people who only use basic social media apps and do phone stuff, so phones don't go obsolete fast for them unless they are chasing the newest camera improvements.
