Therefore sometimes it's easier to just assume they don't have access to certain features.
Sure, but where do you stop? Perhaps people should stop argueing to use "modern" 3-arg open and autovivifying file handles as well? Moose would be right out, now that it's dropping support for 5.8. Perhaps we shouldn't even assume they have Perl 5. (5.8 was released 8 years after 5.000; we're now 9 years after the release of 5.8 - if we let 5.000 coincide with the presumed birth of Jesus, and 5.14 now, 5.8 was released in the middle of the 10th century (Vikings discover America), and 5.10 in the 16th (right after the Middle Ages)).

I think that after 3.5 years, 2 major releases, and an EOL announcement, we should stop the "oh, let's assume they haven't this yet". Let's start assuming they do. Let's stop treating 5.10 as the "new shiny thing only the cool kids have".
