Personally I prefer the traditional glands.
... and, I would say, preferable (if not 'essential') when glanding onto a 'plastic' enclosure.
How else (other than the alternative already suggested) can one get a connection within the enclosure to the armour??
Certainly not essential. In a plastic enclosure you simply need to sandwich the banjo between two locknuts inside the enclosure so that there is metal to metal contact to avoid the plastic creeping and endangering the earth connection to the armour.
It's surely not a 'fad'. If the only connection to the armour is that via the contact between the gland and a metal enclosure, then one has to drill a hole somewhere in the enclose to bolt on a solder tag or eyelet (just a smaller version of the banjo, really!) to establish a connection from armour to the 'earth bar'. Why drill a second hole to attach a 'mini banjo' when one can use the hole drilled (or punched, or knocked out) for the gland and a full-sized banjo??
Well, yes, that is a way of functionally emulating a Piranhna (and the only way before the days of Piranhnas).
