Is the default Android app actively maintained at the moment?

But Android is officially supporting TLSv1.2 since Android 5.0 (API level 21) [https://developer.android.com/about/versions/android-5.0-changes#ssl]. I understand that on KitKat/4.4 the support for more recent TLS is unoffical and varying between vendors so I see the reason on older Androids. But I don’t understand what the issue with Android 7 is? The market share for Nougat is quite high, that’s what got my attention.
