IIUC we'd historically marked stuff as non-experimental when it's 
frozen, largely because ratification is such a nebulous process.  
There's obviously risk there, but there's risk to anything.  Last I can 
find is 260b594d8a ("RISC-V: Add Zawrs ISA extension support"), which 
specifically calls out Zawrs as frozen and IIUC adds support without the 
"x-" prefix.

I can't find anything written down about it, though...
