I was quite close to being up-to-date (some hours), which has been
close enough in all cases until now (that's why I csup once a day,
so I can update to a point close before larger changes and then
do whatever UPDATING suggests).

And in case I screw up, I'll just take pkg_delete -fa and start over :)
Luckily, such updates as X do not happen that often (as far as I can
remember it's just X, Gnome and perhaps KDE triggering large-scale
compiler action).
