The released Ubuntu and Debian distributions usually do not upgrade Qt Creator. Looks like Debian even ships a pretty outdated Qt 5.12...
So the affected group would be people who build Qt Creator themselves.
IMO it is not a big issue to require a newer Qt version for that?

On the other hand branching of Qt Creator 4.13 is only 3 weeks away, so doing that requirement bump for 4.14 wouldn’t delay us that much.
