Actually they work here on a linux box with OpenSuse 15.5. So even if they
are broken on some setups, they are not broken everywhere, or not more 
broken than they used to be.

Also, poper deprecation is needed here, since not only the CLI tools might 
use these. Especially since there is no drop-in replacement.

Yeah, but I never liked when people piped uncompressed data... Not 
everything that the devices support can be serialized, it is extra CPU, 
latency of the receiving app reading from pipe is a question...

I'd be a lot more happy with this if we'd offer some replacement which has 
no issues. Maybe a libplacebo based outdev.
