If we're talking about this sort of thing ... (thread drift)...
Run all the loads in the house through a large gutter or j-box adjacent to the MSP. Then when I come to install a battery system with a backup loads panel, I can install a the backup panel off the gutter and easily and cleanly switch over the loads to be backed up. And then the customer can change their mind about it too, and I can come back (for more money) and change them all again.

120 VAC has been a “standard” way longer than all the things I mentioned.
I built my last house in 1999 when everything I mentioned was completely different than it is today. All the indications are those technologies are going to change completely in the next 10 or 20 years. My current house was built in 1962 and is reasonably serviceable, in terms of having electricity in the quantities needed, where needed. There are issues, but technology has moved in a favorable direction, the same as it has for the past 20 or 30 years — more efficient appliances, etc.
There are some neat gadgets, but going from “stereo” to “quadraphonic” to “7.1 channel surround sound” was bigger than how many feet along how many walls. Dittos for how much network data a computer sucks down, or how many computers in a house. The trend is wireless, but “wireless” has issues, both with bandwidth and security.
