BGE support for BLender 2.8x

I wonder as BGE is no more supported by Blender since 2.8, this means BGE functionnality and code will never get bus fix and improvments ?
Why Blender 2.8x continue to include BGE code when they not support it no more ?

Should not Upbge stop using BGE functionnality ?

Perhaps iā€™m confusing some things :joy:

UPBGE is BGE plus bugfix and improvements.
Blender 2.8 has not BGE code inside.
UPBGE can not stop to use BGE functionality as UPBGE and BGE basically the same
