landuse=forest + ref=* : parcel number or what?

Hello, there.

I hope this will not start a flamewar: I noticed that, despite being widely used, ref=* is not rendered for landuse=forest. I assumed this was used for parcel (compartment) numbers, as this tag seems to fit the definition of a parcel number; nevertheless, I saw on a Github issue of the main style that this usage of ref=* on landuse=forest was unproven and that, consequently, ref=* should not be assumed to contain the parcel number. Besides, it seems that the wiki doesn't document this use of ref=*. Making some use of Overpass turbo seems to indicate that ref=* is indeed used for parcel numbers; there is also boundary=forest_compartment relations, but they seem to be far less used, and mainly in Russia. I would like to document this specific use of ref=*, but, before, are there use cases where ref=* is used with landuse=forest for something else, or are such uses errors, or marginal enough to ignore them?

Awaiting your answers,

Regards.
