I would vote for a solution that reuses as much of existing codebase and 
preserves as many Xfce features as possible. Otherwise will end up with 
a new environment inspired by Xfce, which will either have to be forced 
upon Xfce users or work its way up the adoption ladder like any other 
new DE. Both scenarios are bad.

I would not merge anything more than a few ifdefs into Xfwm4 or other 
existing Xfce applications. There is a lot of value in keeping the 
existing X11 desktop stable and allowing it to evolve in parallel 
without forcing anyone to fork and rename it first.

Why not use xfway as the name of the compositor binary? It seems to fit 
Xfce conventions well, both in the level of awkwardness and poorly 
defined meaning ;-)

I would like Xfway to be a part of Xfce (provided it will not hijack 
it). The question is if Xfway itself is ready for incremental 
development. Research and experimentation is still ongoing (and for a 
good reason, this phase is important), wayland spec and implementations 
(now wlroots, maybe something else someday) are evolving. Some cleanups 
(naming and build system matching the rest of Xfce) would also be nice, 
although this could be done later.
