https://wiki.openstreetmap.org/wiki/Tag:landuse=brownfield is absolutely
not correct, have you reverted? Which changesets?

They are still wood even if burnt so natural=wood should apply.

I have thought about if we should map burnt areas, it's tricky because
while it is surveyable, it changes quickly and the point at when it changes
to no longer burnt is subjective. For those reasons I do think it's better
to store this in another database not OSM. There you can capture the burn
date and degree of the burn.

If you use burt=yes, it means you need to start cutting up your
natural=wood polygons, which I don't think it's worth it.
