Could be, now please point me to patch adding such code to DTS. I would
like to see the real use case for it.

Many other bindings do it. I don't see a problem in creating device
specific schema sharing some parts, if you have some common pieces.

? I don't understand how is this related, but if this is what you want
to discuss then look:
Documentation/devicetree/bindings/usb/qcom,dwc3.yaml

or many other examples. Please open dwc, snps and cdns bindings and look
how it is done there.
