I thought it was stated before that there is no guarantee on the
internal structure of our device tree as the user may explore it (as
long as it's stable for the guest).

We have a lot of "unstable" interfaces that folks yell about every time it changes (like the -help output). Providing a bad external interface and justifying by saying its unstable is just asking for pain later.

  Regarding command line: What are
your worries here? The user can't mess with built-in devices.

-global still applies to no_user devices.

I still think we have more important things to improve than these
cosmetic issues.

What does converting this device to qdev actually add other than an interface that we're not going to be able to support long term?
