I don't really know what to do, so that is why I'm discussing.

It's one of those gray areas.

On the other hand, it is completely possible that all users of this
particular driver actually must have this patch, and then I just
push them to use a deviant vendor tree for no good reason.

Would it be possible that I apply the patch, and somehow also
establish some understanding with all users of the Xilinx
platform that whatever legacy applications are out there
must start to migrate towards using the character device so
this reliance on the numberspace doesn't stick around forever?

For example can we make a patch to some systems like
adding proper GPIO line names to these device trees, such
as was made in e.g. commit f6b1674d570aa1
"arm64: dts: qcom: sbc: Name GPIO lines"

After all that is what I strive for as maintainer, as the IETF
motto says:
"rough consensus and running code"
