Am I just extremely lucky or something?

libpng was installed, slotted on Tuesday May 11
nothing broke.
Didn't run lafilefixer, but did run revdep-rebuild a few times, and
two deep world updates since then. On Jun 28 emerge --depclean --pretend
told me that libpng-1.2 is not used anymore. So I unmerged it (along
with a bunch of other stuff), and ran revdep-rebuild for good measure.
Should I let my breath out now, or should I not be surprised if
this "problem" hits a few weeks down the road?
Cheers,
W
