I'm sure filemaker and apple would have to see it as a money maker. I would guess the reason they got rid of the paid version of Go, is to attract more customers. Maybe after they build a big enough client base for go. They may add that feature to Go.
And to paraphrase what TS personnel have posted elsewhere in this forum: FIleMaker's policy is not to announce new products nor their features/bug fixes in advance.
Well lets hope FM listens to people, I know I am not the only one who wants and are asking for this feature. I know I have been requesting this for I think over a year now......
