Thats pretty much it. Again, its just an alternative way to do what is pretty much the same process, some of that cannot be reduced any further of course. Pick a drive. Set a few knobs. Do install. Wait and reboot. But with the entire process done without needing to use the (ugly) CLI, is now done over SSL end-to-end, and with a renewing cert/host on the other side of it. It’s about providing more modern alternatives and web-driven is the thing people expect these days, especially when the software itself is designed to be managed via the web browser as well. Possible now to never use locally attached keyboard/monitor or clunky IPMI console to go from nothing to running storage.
May be that you are not the target audience, but there are some who find this far more accessible from a new user perspective. It’s like me expecting folks to just like and use vi I’ve had to realize I’m the old man now and that just isn’t going to happen for most folks
