The only issue is see if the filesystem id is use in the proof of work mechanisms.  That is not impossible to address but it would add some complexity to the process.

Totally agree.  I think a good number of Linux people know how to do 
this but even than unless you do it a lot its easy to miss a step.  If 
you're doing it remotely its really never not nerve racking.  For 
someone new, this is going to be tricky and I wouldn't do it over email 
either.  You just don't know what might jam someone up.

For the record, the multiple mount point stuff (like with Ubuntu snaps) 
has not been a thing either.  I've been doing in place upgrades of 
Ubuntu 16.04 LTS to 18.04 LTS, 20.04 LTS or 20.10 and it all just works 
because those are system resources and you as the user to don't have to 
touch /etc/fstab.  The only thing that has been a thing for me is when 
you are changing boot types (i.e. msdos <-> efi booting) or when a drive 
id changes during the move of a file system to a new drive (i.e. 
replacing a drive or imaging to new hardware).

I suppose there are people who mount /var, /usr and other things are 
separate LV's but I would be surprised if the typical Linux user is 
doing that.  I haven't used a distro that does that by default in a very 
long time.  I also haven't installed from scratch without choose a 
custom disk layout in a very long time so maybe I just haven't seen it.
