What seems to be still missing (but I could be wrong), is a

could play and decode ambisonics audio streams (hosted on a audio
streaming web site), then it'd be an excellent start. Something
similar to what audio streaming is for stereo, and that we take
for granted. What went wrong with surround sound in general is
still a mystery to me... But there's hope.
If I understand you correctly, the idea is to stream WXY (to keep
it simple) and have this decoded in the browser, rather than 4.0
directly. This seems to me to be akin to using M&S files rather
than L&R. It involves a further layer of complication at the client
end, and I am not sure of the advantage, other than it reduces data
bandwith by 25%; but bandwidth is surely not a problem these days.
But I am always ready to be corrected!

Decoding in the browser would be for casual use, mostly for binaural
listening, but decoding to speaker arrays would be nice, for exemple
with 5.1 system (as a 4.1 system with a square or rectangular setup).

Why would you not be able to decode ambisonics to a speaker array (for
example 4.0 or 5.1), < from a browser >?
Maybe this is no common option yet today, but why not in the future?
If a browser is able to support 5.1 (stereophonic surround), decoding
of ambisonics to some 5.1 system should actually be no problem. (via
WebAudio)
The usual way to support decoding of ambisonics (only) to binaural is
because the normal application case of ambisonics is nowadays to be
some “ audio track” for VR or 360° video.
Right?!
I don’t think this is just an abstract discussion, by the way. Maybe
such decoding functions could added to Omnitone, for example?
There are strong indications that support for surround sound is
getting stronger, finally. We might be able to help a bit, via feature
request and own solutions.
Best regards
