Also, the reason that in 5e weapons only have a single damage type option is in part to reduce the number of choices a player need make in a turn to facilitate faster combats, and in part to encourage the use of other weapons so that you can't defeat a creature that is immune to slashing by saying I strike with the flat of my blade. So such an extension would be against the spirit of DnD5e.
Yes, flat strikes and thrusts are part of HEMA longsword training, but they are a very minor part, if you are fighting with a longsword, your goal is to deliver a cut.
