I’ve always managed this problem in a different way. I don’t know if my way is better, but it works really well for me.
I treat my powerful desktop computer as my main machine. Then I have a bunch of laptops.
Then I just rsync my entire home directory out to all the laptops.
From there. The rule is quite simple. Any file created on a laptop are considered ephemeral. If I create data that I have to keep. It gets rsynced back the other direction to the main machine.
This process has served me well for at least 15 years now and is supported by a small handful of shell scripts to automate this process
