hopefully it will stop this kind of trouble
https://www.bicycleretailer.com/product-tech/2019/03/15/tire-makers-react-after-enve-issues-warning#.XI6V5PZ2vIUbut I'm not holding my breath.
IMHO the proposed new standards leave a loophole which can possibly leave you the customer with tyres that won't stay on the rim and no comebacks; the rim can be made to size, the tyre can be made to size, and the lack of decent hooks in the edges of a 'tubeless ready' rim will mean that a tubed tyre may not be retained correctly, if it has even slightly stretchy beads. It is one of the problems that is mentioned in the link above, more or less. I don't see a way around this one, apart from to stick to normal rims (with decent sized hooks) if you intend to use tubed tyres.
Some of the other problems with tubeless tyres in recent years are summarised in the diagram below;
