Man, this has taken me forever to respond to. There’s no reason, really, except it was in a run of comments I thought would take longer responses and I shelved for desktop time. ¯\(ツ)/¯

I completely agree about new build - it adds such a small amount proportional to the overall cost. Even when upgrading, I just do a few switches a year, as I notice them. Like, the most commonly used ones get replaced first, but after that it’s just when I find myself thinking, “I really need to automate this one” that I change them. I swapped out several wall sockets after the first Christmas in our current house, for example.
