make a --really-best-format option

Description

The format sorting is documented to have the default:

lang,quality,res,fps,hdr:12,codec:vp9.2,size,br,asr,proto,ext,hasaud,source,id

mentioning that hdr:12 and odec:vp9.2 is set because better ones aren’t supported by many devices yet.

That seems rather unfortunate, because people expect that per default they get the “best”, while in fact they may not in some cases.

Of course one could just override that with:

--format-sort 'lang,quality,res,fps,hdr,codec,size,br,asr,proto,ext,hasaud,source,id'

which has however the drawback, that it also overrides any extractor specific sort order (which is usually there for a good reason).

So it would be nice to either have something like a --really-best-format option or alternatively, really use the best per default (and perhaps provide a compatibility option that allow people to select formats for older devices.

Cheers.

or better way is to make best really the best by using av1 and add a --i-use-dlp-on-a-toaster-even-in-2020s option.

The HDR restriction makes sense to use permanently. While DV is technically better than the other formats, it is terrible if your display does not support it. So I want users to specifically ask for it if they want to prioritize it

Yeah, DV is a proprietary format. But dual-layer HDR10+DV streams (DV profile 8) should probably be prioritized over HDR10-only.
