True, as long as they're truly standalone.

Maybe the compromise is:
1.  Groups of related stabilizations should be grouped.
2.  Groups of only unrelated stabilizations can also be grouped.
3.  You must not try to mix #1 and #2 in the same commit.

As you say individual packages are easy to revert anyway.  However, we
wouldn't want 100 of those to be mixed in with 50 packages that all
needed to be coordinated, because those 50 aren't easy to revert.
