Addressed all 3 cases (WMA, M4A, VorbisComment-based formats) in 1.4 beta 17, thanks for your patience.
As you've probably guessed I don't personally use this field, that's how it was working so badly to begin with. Please do post if you find any more issues with it.
Thanks again for your work on this.
I tested all file types mentioned on hydrogenaud.io's Tag Mapping Page for functionality with the beta release you directed me to (foobar2000 v1.4 beta 17), and all file types work except one: My .ape file with a APEv2 tag is still not mapped correctly in Foobar2000 v1.4 beta 17. Foobar2000 v1.4 beta 17 is still erroneously mapping APEv2 tags to Content Group rather than the correct field Grouping --although I've seen some software cut corners and map it to GROUPING. I don't know if these fields are case sensitive, but I imagine you would know about that.
I can only guess that Scaramouche is referring to ape files in his post (msg=958586).
Also Opus codes 12-20 kHz range in just 2 freq. bands of total 20 (10% of total bands). Add to that band folding and 12-20 kHz range is coded just at few-to-several hundreds of bits ( less than 1 kbps).
So it's very cheap for Opus to code this range starting from somewhere ~13.2 -14 kbps.
P.S. Also I suspect that SWB can be pushed down to ~11-12 kbps (at least for speech) because 1.3RC SWB@13.2kbps is on par with an older 1.2.1 FB@16kbps

I scored one of these at Goodwill over the weekend for $49! Banged up headshell, cartridge, missing stylus and slipmat. But otherwise, the tonearm is still in good shape, belt was down there and it starts/stops/pitches as appropriate. I replaced the headshell with a $10 one from American DJ, my spare AT3600 cart and stylus (unscrewed it from a Gemini headshell combo, because it does NOT fit this and other universal tonearms, BTW), and a $12 slipmat. Worked like a charm. I did a sound comparison with a Sony LX300USB and the overall quality is the same, though the Sony is maybe a notch louder. I'm using it just for everyday playback. It sucks that it doesn't come with a dust cover, but oh well.
