Uhm, I seem to have missed that bindings are deemed more "flexible" as
long as they are coupled to in-kernel dts files? Is that discussed
somewhere? I do wonder about it...

Well patches like this are sent out but not commented on from
the perspective of binding stability. So of course, they get merged.

Have a look at this commit:

    mmc: dt: Consolidate DT bindings

This is deleting custom properties from DTS files without
adding any code to fallback-support them on old device trees.

(Actually I like this commit a lot, since it is removing custom MMC
props and replacing these with standard bindings common for all
MMC/SD controllers, but ...)

I think there are more examples if you git log on arch/arm/boot/dts...
