One other point: the loss of SD and CCC (except for Intel-based Macs) is a "core" operation that one must do, ie, make backups. Yes, there is Time Machine, but there are just too many advantages to using SD and CCC. That loss is definitely a bummer!
Just to be clear, the loss of functionality in SuperDuper! and Carbon Copy Cloner is the ability to make a
bootable backup (clone). This is a significant distinction from Time Machine. So far on Apple's SoC M1 Macs (to date) SD and CCC can make backups of the data portions of the drive.
