...so, to add a bit of pointless chatter, while I don't recall exact messages
(though IIRC, they were different), back in wine 5.9, I've stumbled upon a game
(though, once again, no longer recall the title - though definitely not on this
list) that also needed more streams than 16. Also randomly changed it to 32 and
carried the patch ever since.

I've seen these errors in many applications, but it never actually matters. I
suspect they are all using some engine which periodically saves and restores
all state.

Do any of these applications actually misbehave?

Only Fallout 4 and GTA V use own engines all the rest based on Unreal Engine 4.
I didn't see misbehaves at least for games I've checked. If this really doesn't
matter maybe we could change it to WARN then?

Yes, changing it to WARN for the getter, and when setting to NULL, would be a
good idea.

If that will have a bonus effect of actually crashing when accessed, that
(somewhat counterintuitively) seems like a good idea. That way we could tell if
those are actually used.
