Was it pure failure,or today's sick fascination with 'mobile' that would lead a 'modern-replacement-for-X' project to have "multi-monitor issues"?
Neither. One of the things being glossed over or ignored by most of the discussion here is that Mir is working absolutely fine (including with multiple monitors). The issue causing them to "undefault" Mir is that XMir is not as complete and stable as they would like when apps that require X11 try to operate in multi-monitor mode (XMir is a compatibility layer between Mir and X).
In other words, the "weirdness sometimes experience in that area with classic X" in fact IS the problem, or at least the major contributing factor. Their compatibility layer isn't handling all the weirdness edge-cases.
So if you have a single monitor, or don't plan on using any X apps across monitors, feel free to install Mir/XMir and move on. It's being made optional, not going away.
