We don't have an infrastructure to do this right now.

Some ports do this on an ad-hoc basis.

The usual needs are to have a DAG relationship between different parts of the system so you can turn on and tune clocks, as well as power blocks which may be necessary to power the clock and/or basic-blocks in the SoC. The latest chips have grown quite complex.
