Nostalgic mid 90s project POVRAY rendered for fun...
I used to have this on a DUAL HOMED SVGA setup under XWindows
on my bench...

And none of this stuff in any way or form addresses the OP's problem. You can open a single app multiple times without any such "hacks", the reason why it doesn't work with KiCAD by default is because you will corrupt your data if you do that. It has nothing to do with the display server.
I am also wondering *IF* we are talking on the same kind of setup...
or we are on the same page...
I never mentioned the stuff you rant about...
as being replaced or ranting this that..
Fact is attached
My setup evolved from what you call XFree86.
That bundle was prevalent in distros at 90s.
Xorg is just another name to the very same protocol stack
(all above layer 4) in which you do require your apps compiled
with -lXinerama to at least support multi heads.
Despite that being a client-server only model the setup
requires all protocols available at compile time.
My setup evolved from that and trying to bundle systemd and
wayland was a huge waste of time in my case.
Thus the 2 cents of advice I think are very handy.
Far from being rants..
And take a good look on how basic networking is required..
If you wonder how X relates to network ... or SSH
All graphic ready in my setup
so you just don not patronize me about non sense terms and basic stuff.
Kinda of that do not fit at all
For the record currently I have successfully upgraded my
scratch system to LLVM12 + MESA20 + GCC10
In which I totally dropped systemd and all wayland protocol stack
because they are a huge messy sack of problems...
All already working fine as long as all clients are properly
aware or all required networked protocols at compile time
and got rid of those problems
For the record BOTH are working Multi Head and Multi Homed
Also for the record
I never ever had any issue of corruption because
when doing that.. I take the proper measure at login saving
proper state and isolating things properlyKinda a newbie stuff think someone will open same project
2 or 3 times doing random changes... pathetic.
2 cents of who already trailed that
for those interested in succeeding properly
