Metal 3 or newer Metal support for old devices

Hmmmmmmm so I’m using an MacBook Air 2015 recently and surely its now out of the metal 3 support list just like Phillips so I’m kinda curious ‘bout is apple gonna extend or is it possible for apple to extend the metal3 support list in the future or we could say is there any hope or ways for our ‘unsupported’ devices to use the metal 3 ? May be some day in the future? It’s mainly cuz the system animation now is soooooo poor there’s like many ‘unknown’ issues like drop frames, lags and so on while the graphics card and cpus is with a super low (almost idle) usage, and metal 3 is with such that a huge update and mainly cuz ive saw the difference on one of my friends 18 MacBook Pro the system animation there is with a HUGE upgrade and improvement it became so smooth relatively mostly caused by the metal 3 improvement on Ventura beta, soooooooooo yea. And how’s the possibilities? And if not is there gonna be some new, issue-fixed or animation-optimized version for those devices which out of metal 3 support? Thanks in advance. :D
