Starting around a decade ago, I think. When I was originally given
this advice there was no detailed explanation available as to why it
was needed. However, I rebuilt my kernel a few times and was forced to
merge that package to get X11 working again, so causation was
established.

Recently I can verify that I haven't been doing it manually between
kernel upgrades.
