You were trying to educate someone on terminology, but used it
incorrectly yourself, for which I corrected you. So yes, it is a matter
of terminology – you turned it into one.
tmux is not a window manager in the X11 sense, which is really the only
definition that makes sense in this contect (this is the mailing list of
an X11 window manager, afterall). Also, X11 window managers at least
_have_ a definition; if you want to consider tmux a window manager in
some other sense, then you owe us that definition, but that really
renders your original email pointless in the first place (why educate
someone on terminology you made up on the spot?) Lastly, tmux never
refers to itself as a window manager (because it isn't one), so
insisting on it being one means that you somehow know better what tmux
is than the tmux developers themselves.
And for the record: what defines an X11 window manager is that it
selects SUBSTRUCTURE_REDIRECT on the X root window. i3 does this, tmux
doesn't; hence, tmux isn't a (X11) window manager. That's not a matter
of terminology or opinion, that's just a fact.
Under Wayland, the equivalent would be called a Wayland compositor. As
Michael pointed out, i3 has no plans to move to Wayland.

tmux isn't a window manager, it's a terminal multiplexer
That's a matter of terminology. Given that tmux itself
refers to its ...windows... as "windows", and can split
them horizontally, vertically; all with different workspaces,
I find it reasonable to refer to it as a TUI window manager.
TUI vs GUI in the sense that the display unit is characters

a X11 window manager, which is what i3 is.
So once wayland replaces X11, will i3 then become a wayland
window manager (or whatever terminology *they* use)? GUI
window manager is a slightly more general term that covers
