1.16 or lower versions have disadvantage from players on 1.8 with higher/lower version

Players playing on Minecraft 1.8 have reach of 3.4 blocks.

Players on 1.16 have reach of 3.3 blocks.

It has big impact (around 4%, which is huge) on fighting. In almost every situation 1.8 player can hit you, but you can't hit him. 

Please add reach of 3.4 blocks to the future versions, to bring back balance between all players.

Thank you.
