Maybe we could use std::boxed::ThinBox or something similar to further reduce the size from 16 to 8 bytes? By storing the slice size on the heap.

There is also thin_vec::ThinVec, which I introduced to the compiler in #100869. Unfortunately, getting any of these kinds of changes to show a clear performance benefit has been hard.
