The Star left cluster are primarily operations that pair the left hand on the keys with the right hand on the mouse. This derives from Engelbart's Mother of All Demos with the left-side keyset paired with the right-side mouse.
Sure (this is demonstrated in the linked video, for instance) but the ZXCV group is pretty similar in that respect. Even for operations which involve the mouse it's preferable to drag only one hand far away from its home position, rather than both of them. (Especially since the video evidence https://www.youtube.com/watch?v=Cn4vC80Pv6Q seems to suggest that Star users tended to move their left hand only after making the mouse selection, instead of prepositioning it.) And the Star's Undo key, which presumably doesn't require help from mouse input and is likely to be needed after a non-mouse action, isn't placed any more conveniently near the home row: it's simply in the right side-cluster rather than the left one.
Not sure if this was ever supported system-wide in any way, though.

Early Mac design was excellent overall, but decided not to include these keys (maybe they were leaning towards Smalltalk-like context menus?), and then seemed to go into more cryptic and power-user in-the-know keyboard direction (like with the 3-icon key including special support for flipping burgers):

(Yes, they could have just replaced the "regular" function keys with copy/paste keys, but I feel like that would have gone over about as well as the various times they've, uh, tried to replace the function keys)
Conflating meta keys with control keys is one of the more pernicious abominations Microsoft saddled on the tech world.
Shift - Control - Meta - Super - Hyper. Each has its place.
I bind Delete to F12 on every machine I use. It's a wonderful thing.
