That's minecraft is "smoothing" the movement between the start and end, for an instantanious teleport, you need no smoothing (no frames in-between teleports)

Well I have actually quite some situations where I could really benefit from having a smooth teleport I'd rather even have some in-between frames than not having a smooth teleport.

Why don't they just add a special tag for "Instant"
Like: /tp (target) ❌ 👍 (z) [instant] or /tp (target) (2nd target) [instant]
It defaults to false, for a smooth teleport.
If set to true, it will teleport without moving the hand and it won't have any in-between frames.

It seems like a good idea to me ^_
