@atoponce In this case it probably doesn't matter, but this justification in general is bogus.
Often, it means the bug was introduced in like 5.4, and folks using the functionality are still using 4.x or even 3.x because that's what supports their devices or because there was no compelling reason to upgrade.
And then "feature they need was removed because the fact that it was broken on 5.4+ proved nobody was using it" ensures that they stay on the old version forever, in a self-reinforcing cycle.
