Hot Swapping batteries is actually surprisingly good for the life of the battery if done well.
Rapid charging the battery does do permenant damage over time especially if you fast charge every time. Whereas if you can hot swap a battery and have a suitable stockpile of them you can trickle charge the battery over a couple of hours instead of 30 mins and prolong the overall lifespan of the battery. Even slowing down the charge rate to 1 hour reduces wear on the battery significantly. Plus, without time pressure from a customer, more time could be taken to replace damaged cells or blocks in a battery so that one pack will more effectively use the whole battery up instead of throwing away perfectly good cells.
See, for me, I rapid charge like once a month. All the rest of the time I use my home charger or even a granny lead. 10A granny charging is absolutely fine overnight. But for the size of the E-Berlingo, the battery is a bit small and I know all kind of new batteries are coming. More kWh for the same weight/size, less degradation, safer, etc etc. If I knew the car was designed with battery replacement in mind, I'd worry a lot less about it being obsoleted prematurely. These cars are all black boxed stuck together. It's not built with repairing and upgrading in mind.

At least 'some' minimal standardisation so we can exercise the #righttorepair

Exactly. I want things, especially expensive things, built to be repaired and upgraded. Not vendor locked and with built in obsolescence.
