"Nobody" uses syscons (sc) anymore, as vt became the default.
Sure, it cannot do everything sc could do (for decades, in
the proper, predictable, and expected way), and there are
significant limitations and inconveniences (screen size
definition, font selection, colors etc.), but any system
that runs X will also have to use vt. In addition to vt,
the correct DRM module usually has to be loaded, plus of
course the appropriate driver for X needs to be installed
(for example, xf86-video-intel).
Only for systems that do _not_ run X, choosing sc is still
in /boot/loader.conf, changing the default setting from vt.
