If Liquid Glass was inspiring, efficient and beneficial it wouldn't have to be mandated.I'm however, disappointed at Apple for not enforcing it.
Maybe it's harsh to small developers, but there should be a threshold when you are mandated to incorporate the liquid glass design into your app or face not approval
It would be attractive and third parties would eagerly adopt it.
To suggest it should be mandated is akin to cramming it down people's throats. Not a good look.
