There was no inference that was the case. However, the lion’s share of issues with Wayland seem to come from users of older Nvidia product. That’s just how it is.
And, yes, that’s no doubt one of the reasons it remained as a possibility, even after the KDE switch to Wayland. Unfortunately for many Gnome users, that wasn’t even an option.
It was a legitimate addon to your comment. Clearly you misinterpreted it to mean something else.
If you’re interested, I believe @DeLinuxCo has at least one Manjaro spin that uses XLibre – it might be worth looking at.
