We'd all like to avoid squishy human users if possible but sometimes it's unavoidable :-D My feeling is that cephfs should be mounted natively only on trusted, "tightly coupled" systems, whose availability is comparable to that of the servers. So on a typical user laptop would be a bad idea, but on a big visualization workstation might be OK, or on the always-on identical desktops in a single CAD/CGI/EDA team might be okay too. Slow/naughty clients generally only cause pain to other clients in the same filesystem, so if you do have some files accessible to workstations it might also be prudent to segregate them in a separate filesystem (currently no cephX way of enforcing that, but if you basically trust the workstations and just want to isolate them in case of bugs/outages, it's okay).
