Not supporting command line options isn't going to fly.  While VM 
managers probably can and will generate config files, not everybody uses 
management software.  And having to hack the dts and run it through the 
dtc doesn't look like a reasonable solution for users to me.

Also currently qemu lacks an option to specify such dt directly.

Sure.  You still have to link them.

Ok, sounds like there isn't (yet) a plan.
