I guess I can understand that you want your /usr to be resizeable, but
really, life is so much simpler when you just go ahead and create a 12
GB root filesystem (and no separate /usr) and be done with it.  The
days have long passed when that 10 or 11 GB of wasted space was
anything to worry about.

I always thought reads were pretty harmless and it's mostly writes you
have to worry about (both for bugs in the OS FS, and for the physical
media).  And both / and /usr should have very few writes,
percentage-wise.

I used to think keeping / fully self-contained was useful.  But it is a
non-zero amount of effort, and I'm becoming convinced that these days,
the separate /usr is going the way of the shared /usr/share.
