I can't recommend it for desktop use, but it is possible to use it as such.
IMHO it really shines on dedicated, small VMs or for headless SBC use cases.
There's only 5 daemons running after the installation (provider in brackets, the installer asks which one for ssh and ntp): - init (OpenRC) - ssh (dropbear or OpenSSH) - ntp (chrony or busybox) - crond (busybox) - syslog (busybox)
The diskless mode it offers is ideal for SBC's or other use cases with SD-cards or such.
So it's niche seems to be with very lightweight or hardened servers.
