which I mean Activities/Places/ActivityMapper), otherwise it probably
wouldn't exist. The problem I have is that GWT-Platform isn't
supported by Google while their MVP is. Maybe GWT MVP isn't entirely
sufficient but it has worked well for us. It's not unreasonable to
assume that Google will enhance it in the future. What happens then
for development shops that have migrated to GWT-Platform and they are
tempted to switch back? They have existing code that uses another
framework and developers that are used to the non standard package.
Messy right?
