I never had "an issue" with my E39s or E90 either, but I still plugged them in every now and then, and they often charged for HOURS before the trickle charger indicated they were full. Sometimes close to 24 hours depending on how long since I plugged them in.
Before concluding there's an "F10" problem or a BMW problem, try it on a few other cars and see if they take any charge or if they're all sitting at 100%. Just because warning sirens aren't going off doesn't mean it wouldn't be best practice to do something like trickle charge occasionally.
How many people have "issues" with F10s? The "discharging while stopped" messages are a malfunction in the car, that's not a short trip issue. A "replace battery" message means you've worn it out. The only error messages related to this so called short trip issue would be "Charge Battery", and it's not like the forum is full of puzzled people wondering what "Charge Battery" is all about.... For what it's worth, depending on how it's optioned and whether pre or post LCI, an E90 can tell you to do that too as far as I know.
Going back to E39 and E46 days, prior to IBS, there were owners stranded sometimes. They would usually be chronic short trippers who then left the car in an airport parking lot or their garage for 3-4 weeks and came back to find it couldn't start. This is usually where IBS-equipped cars have already shown you warnings, or shut everything down so you could at least restart. Some also had malfunctioning aftermarket electronics that they didn't realize were draining their battery while parked - another place where IBS helps.
