Cool, thanks. According to [3], FF no longer needs patches though.

I'm afraid you're right regarding electron/flutter based apps, if they be=
come waylan native, :( Hopping not becoming true though.
BTW I thought for general desktop sharing (not app specific like slack or=
zoom), one could always use wayvnc [1], though now that I read the descr=
iption ("VNC server for wlroots-based Wayland compositors"), and also loo=
king at [2], it doesn't work for all compositors, except by sway, perhaps=
wayfire, and other wlroots based compositors. But any other solution, l=
ike the Gnome one mentioned in [2] most probably is based on pipewire, :(=
Although my goal was to eventually use kwin, perhaps I'd have to stick =
with wayfire, if I'm to use wayvnc...
Sounds like you're right though.

Does it mean, that if apps sharing video and audio, for video or audio ca=
lls for example, become wayland native, such as slack and zoom, then by d=
efinition pipewire's video and audio must be used? So far I've avoided u=
sing pulseaudio, and I'm afraid pipewire's audio looks pretty much like a=
nother pulse-audio, :( It adds a server as well [4], and it's a server p=
er user, instead of a global root one (for several reasons, I don't like =
this either). Also, for pulse by default apps, which haven't been tweake=
d to use alsa instead, one needs to install pipewire-pulse and then make =
sure the pipewire-pulse.socket is enabled for each user [5], which might =
require some S6 service assistance any ways. For plain alsa apps, it see=
ms OK to just install pipewire-alsa, and it sounds easier to tweak pulse =
by default apps into plain alsa apps, and avoid having to deal with the p=
ipewire-pulse.sockets...
So in the end, it seems some S6 assistance with those sockets might becom=
e handy (I guess they need to be created when each user logs in, not sure=
)...
I don't like these models, :( But it sounds like when everything is wayl=
and native, there will be no other way, right? Really sad, at least for =
me, :( Not sure if I like the wayland ways now, but Xorg is no more any =
ways [6], :(
