understood, but I thought that these days the majority of installations 
are in fact single user machine installations where the "sys" part 
really serves typically a single user.

So my thought was that you get already a huge improvement if a "sys" 
update is checking if the current user also has local formats and if so 
warns about that and/or offers to update those as well

but isn't it the case that if I install TL on my laptop (for all users, 
even though I'm the only real one) that then all future updates will 
just update the formats in the sys tree which is precisely the problem 
we see?

and honestly the fact that way back I was warned that I do a local 
install may not be something I remember by then (like the user in this 
thread who didn't remember having produced the local format)
