I think it may be good to validate but not provide. There is no Linux provided ACPI table right ? So I get the point to validate a DT.

There's "Linux provided" ACPI tables when someone has to decompile, fixup and re-compile their DSDT files.

Or perhaps a better way to think of it is that yes, there's "Linux provided ACPI tables" when vendors are developing their hardware and correcting their ACPI tables. Same thing with DT, by and large (as overlays and secure boot are a can of worms to worry about later).

Secure boot enabled Linux does not permit this model. Side loading of DSDTs/SSDTs is disabled by the hardening patchset that all the distros carry for secure boot enabled kernels.
