Very few people are actually affected by Android 2012, but the marginal number of active devices is worth replacing.
Today, there are no great names on Android, and the arrival of new features may have slowed down compared to the old days, so people are often more interested in a security package update than in the era of Jelly Bean, which was launched in 2012. Each release brought more significant improvements, such as the Vsync image update Google Now, Android Beam now discontinued, Notification system overhaul, Lots of audio improvements (external DAC support, multi-channel audio, AAC codec support).

Android versions 4.1 to 4.3.1 now work on less than 1% of active devices after 7-8 years, but if someone keeps such a device for ease of use, even in a work environment, it might be worth considering switching devices since after Security updates will expire, Play Services will also be completely turned off on them, and the latest version of most applications can be installed on them only if the developer processes these old versions separately.
