Indeed, I recommend to use iwd instead of wpa_supplicant. There is no
active development happening in ConnMan on the wpa_supplicant
plugin. That means the wpa_supplicant plugin might work perfectly fine
for your use case and there is no need to use iwd. But don't expect any
big help if there are problems with wpa_supplicant.

Hard to answer as there is not definition of 'stable enough'. The best
advice is to test your use cases and figure out if it fits your
requirements.

This is a question for the Yocto mailing(s) list.

There is none, but there is not much you need to do. During the
configure step you do something like

./configure --disble-wifi --enable-iwd

That's all.

There is no change in ConnMan's D-Bus APIs. Depending on your use cases
you might be able to remove the ConnMan from your design and only use
iwd. This is the case when you are only interested in WiFi networks. I
know some project went this way as it makes their system simpler and
more robust.

No worries, I still hope someone with writing skill steps up at one
point and helps out at this front.
