Would you do the same? If not, why not?
Two things:
First, asking respectfully, have you looked at code? I've done a couple houses recently (homeowner permits). With the exception of our kitchen where I F'd up and cracked a tile and in our living room where we put the Christmas tree, in my experience, current code is more than enough.
Second, I recently had our bedroom down to studs also. (I'm NEC2017) Behind each night stand we have single gang receptacles with two USB-C ports. We also kept the one behind the bed for heated blankets during cold months.
Reality for us: Both have iphone and iwatch. We use long Apple usb-c cords to the receptacles for them. That looks clean/nice. Winter we use center (behind center of bed) receptacles for heated mattress thing. We also have power strips plugged into the receptacles behind night stands.
Her Apple laptop cube thing won't fit (and is pain in the *** to plug in/move). My laptop cord will fit but I often work very early/late (overseas stuff) and when I get up the dogs go crazy so it's nice to have a power strip where I can plug in when I need it or unplug and sneak out while she's still sleeping.
Honestly: USB-C receptacles behind the nightstands were a waste of money. We should have put single receptacles and plugged the night stands into that. I wouldn't waste your time with the 2-gang stuff. 1-gangs behind night stands, a single gang behind the bed and call it a day.
I put doubles behind the nightstands. It's definitely worthwhile unless you're a luddite who still uses a wind up alarm clock and a corded landline.
I guess I'm that luddite... ironically I legit have a landline so I can have a fax machine.
