The AOSP master branch is already reflecting the 2021 work in progress.
For the Android 11 (2020) release,
https://cs.android.com/android/_/android/platform/build/+/be01cf841e95b8ae396625486b8fb746e5e71492:Deprecation.md;drc=97ec8127081ce0e4b372349caa513ccde9f0fcf7;bpv=0;bpt=0
will
be the state:
I checked the doc in build repo
https://cs.android.com/android/platform/superproject/+/master:build/make/Deprecation.md,
Google is coverting the make to soong.
Will google convert all BUILD_* to soong in 2020 release? If not,could you
give us a deprecation plan list in 2020 release ?
Thanks
