I don't see how one might struggle with learning how to use distrobox. Of course there's some learning curve, but if one wants a normal Linux they might as well use stock Fedora. All one needs is to create a terminal profile that launches `distrobox enter container`.
(I used to use bluefin until recently, when a regression on distrobox forced me back on Silverblue. I could not for the life of me force rpm-ostree to downgrade distrobox to 1.5.0 vs the 1.6.0 bluefin ships with; I reckon it's because bluefin is a container rather than an ostree commit, and downgrading packages is still unsupported)
