Hi folks, author here. Happy to answer questions.

I'm sure if you're missing anything useful diagnostics-wise it's worth a FREQ though. A lot of us also do travel with our laptop to numerous FOSS events all over the place and encounter sub-par networks left and right, after all.
Somehow or another, if you open a file in Dolphin on one of these network addresses in a non-KDE application, it seems to pass it through using a FUSE filesystem, which does work somewhat but not 100% in my experience (I don't really know how this works or remember when it falls down). The terminal view in Dolphin also `cd`s to this virtual directory.
Of course, if you really really wanted the sshfs mount for some reason, then this workaround doesn't help you.
