I'd like some guidance on the usage of Spring Webflow for a financial Enterprise application. If for example a system needed to to accommodate 500+ users, are there any adverse affects of building a solution completely with Webflow? Webflow is excellent for navigation control amongst other things, but are there any drawbacks in comparison to an MVC/Webflow hybrid? From what I've read, the Spring documentation suggests to use the MVC/Webflow hybrid approach where Webflow is simply used to control complex navigational scenarios. However, Webflow also seems to work quite nicely for simple maintenance screens where complex navigation is not required leaving me unsure of which is the best approach to take.
