I have been using getent in Solaris since the 90s, before Linux even existed and history section of getent mentions:

HISTORY
     A getent command appeared in NetBSD 3.0, and was imported into
     FreeBSD 7.0.  It was based on the command of the same name in Solaris and
     Linux.

So I suspect Linux Mint and KDE Neon might be the anomalies ;-)
