When did link aggregation become "fancy corporate garbage"?
All my switches are bonded to one another, and it was handy when something snapped one of the fiber runs. That side of the house kept connectivity until the weekend when I could crawl around and run a new cable. (Never did figure out why it broke, though. Guessing the house shifted in just the right way.)
It would have hardly been the end of the world if I had to wait, but if your kit can do it, why would you not?
I would not detract from your network going the extra mile. I suspect that for most people, the value-to-effort ratio of link aggregation just isn't there in a residential setting.
