you're acting like this wasn't intentional
I don't mean to imply it isn't. I wouldn't be surpised. I just have no evidence of such. CA TLS is messy and pretty much impossible to get right even over medium timescales.
But it does reminds me of when Garmin GPS would make the storage filesystem limited to say, 3GB of read size, then offer "lifetime map updates" while knowing that in a few years the new map size will not be readable on old Garmin devices.
Maybe it wasn't which is worse, meaning Microsoft despite being in the top 10 most valuable companies in the world can't even get these basic details right. I think assuming this was intentional is actually giving Microsoft the benefit of the doubt tbh.
