--- Comment #7 from Jan Beich <jbeich at FreeBSD.org> ---
Bug 227423 will tackle libwayland-egl issue. WAYLAND=on is still required for
other things (Vulkan, libEGL). So, let's change the default to facilitate
testing/maintenance.

What benefit do you expect from neglecting Wayland support? X11 isn't going
away but in future more Wayland-only apps may appear.

Let's not undo bug 218799. Splitting ports adds to maintenance cost and
introduces intradependencies (i.e., dependencies in-between parts, including
loops). Moving into a flavor won't work until the ports framework supports
package alternatives aka variable dependencies, so direct and indirect
consumers don't add up in a conflict between flavored and unflavored
dependency.

Not Wayland but libEGL. Affects only sparc64. Is it that hard to add
OPTIONS_EXCLUDE_sparc64=WAYLAND ?
