yes if every package followed this sadly thats a more and more
diverging case now a days.
so do we diverge and it there a compelling case to do so. I would do
it if 80% of our usecase was this one
but this seems like a one off thing so either we find a better
solution or we abandon it. In my opinion
such a thing should be a configure option disabled by default and
whoever has the usecase for it
can enable it but not default

there is a use case where now people are asking can I use this fedora
prebuilt rpm with yocto/OE
and so on and if we diverge too much on root file system layout by
default we can get sidelined.

Linux was never supposed to have / and /usr different to begin with
