player height POV Parity

currently, ported mods/addons such as Origins (with the inchling race), and shrinking mods in general, Bedrock players cannot go in first person mode and be at the correct height. Most developers of these mod ports and addons use the experimental cameras, but it is very much Not an ideal system. i'd like to be a few pixels tall without having my first person be an entire block and a half above my head. we're already able to change the height and hitbox of the player, let us adjust the first person perspective accordingly, please.
