Yeah, that's a great clarification. The way I've phrased it implies that they're somehow incompetent for not immediately jumping to the newest version, which is not my intent.
I more so meant it as a way to figure out what their plans are for software lifecycle. All common languages (as far as I'm aware) deprecate old versions at some point, after which there are security implications for not updating. Asking what the long term plan is for changing versions and keeping up to date (however big of a priority that is) can provide some insights into how aware they are of technical chores that may be important but aren't feature related. I'm personally more interested in how a company thinks about their answer than what the actual answer is.
For example, I once spoke with a company that used PHP 5.5 with substantial tech debt. Their long term plan was to rewrite the whole platform as Go microservices. They didn't seem to realize that this would be a multi-year effort if it ever happened and that PHP 5.5 was already past its end of life date. The solution didn't fit the circumstances. That told me quite a bit about their engineering organization.
