The vendors need to add the data validation and formatting, etc. there their
product. Different people will want to use the product in different ways,
and these same people will all have different ideas about development. The
vendors need to make their products flexible in order to ensure they are
used.
So, for example, if one prefers to perform data validation on the server,
well - that's fine. One doesn't need to use the data validation built into
the UI widget.

That reminded me of the phrase "Separation Of Concerns"...
I like that phrase, Aaron. "Separation of Concerns".
Of course, it's human nature to be concerned about everything at the same
time, which is stimulated by living in a complex world. And the male
species responds to it with a grunt and a shove, while the female species
responds with about 8 distinct facial expressions in 2 seconds, followed by
a long stream of verbal expression containing so many different ideas that
the male species begins scratching his head ;-).
I guess my point is that there's a natural tendency to blend everything
together. Even though you try not to. And I may not be able to pinpoint a
specific example, but I suspect there are a number of major vendors and
players in the UI widget market that have combined UI layout with data
validation and formatting, and mapping with data stores, into one component.
