Allow overlays to be applied to any DTB. This adds around ~40% to the
total size of the DTB files on average.    

Yes, I will move on to this solution for now to avoid too many complaints
about the devicetree size increases.  

I have done some experimentation with this patch (on top of v6.19 and our
private defconfig) but could not find any DTB size increase.

Does it require another patch or CONFIG change?

No, but maybe you had already the "DTC_FLAGS=-@" option enabled while building
you image.
This options add the "__symbols__" node listing the symbols to the built
devicetree:
$ fdtdump arch/arm/boot/dts/ti/omap/am335x-bonegreen-eco.dtb 2>/dev/null | grep symbols
