Height / Weight values tied to anything?

[english09]

Since Pokemon made its way onto the Switch (LGPE / SWSH), Pokemon now have individual height and weight values.

These values are only relevant in LGPE, yet still exist in the Pokemon's data structure in SWSH (and change from one Pokemon to the next, even of the same species).

Clearly it's a random value that is assigned, but is it tied to anything? Could it affect legality?

Wondering this as well.
