I've reasonably extensively tested this, but a 4 eyes cross code review and/or manual test by others before merging this in certainly still wouldn't hurt. @vishwasbabu and @mgeiss if you have no objection then I’d like to merge this into develop in the coming 1-2 weeks, if for no other reason than that I’ll have less time to react to related issues after that for a few weeks - so I'd be grateful if you could have a look ASAP, and shout now if anything seems seriously fishy / clearly NOK to you.
