Well:
It was an explanation. Myrlyn is a good sample of the situation: if someone works in a tool replacement, the tool will be there 
Nobody here is against this. But if no one does the work, there won’t be one.
2,3. Cocking is a system administration tool, not a desktop/laptop administration tool (by now, who knows?).
In openSUSE you have: Search
You can administrate your remote server and also your local machines including your children’s laptops. But you can’t use it to setup a printer.
openSUSE/SUSE had YaST since 30 years ago, but people think Mint is “easier”. Newcomers need things working.
Well, with the time we’ll need: a YaST Partitioner replacement(1), an easier upgrade method, maybe think about an easy way to sudo, a new Boot tool, a new config files edit tool…
No problem here
(1) Some things are about Agama installer anyway. For example, LVM+Snapper setup.
A good openSUSE partitioner tool needs a good btrfs capabilities manager.
There is cockpit-storage but it’s far away to be a good disks editor.
