+I do sometimes wonder why we don't relax the definition of "safe" upgrades
+to include installing new packages but still not removing old ones. I know
+that many of my uses of dist-upgrade are just for when something grows a new
+dependency that I didn't previously have installed.</p>
+
+<p>(Of course this wouldn't always help as it wouldn't account for a new
+dependency that conflicted with an old dependency, but never mind. It would
+certainly do wonders for the metapackage case.)</p>
