A: FileMaker's track record for discussing things about the future
B: Their parent company's skill at being tight lipped
C: That anyone who might know anything will pretty much certainly be under an NDA to not say anything about anything at all
This seems like a perfectly futile thread in which the speculation, with a small smattering of potential frustration/bile/whinging and lots of 'how dare FMI change things' - which is probably not an actual discussion but rather a chance for others to tout their favourite opinion will be hot (as in heated) but lacking in any substance.
Feel free to fill in your own response, starting:
Its terrible that FileMaker wants to remove/delete......
The only thing FMI has stated : FileMaker Product Roadmap 2018 which state that will be a UI redesign and that Rest API will be added. A trial Rest API is currently in FMS 16. I agree with jrenfrew, that this is just false speculation.
