Not really. Now when I want to uninstall something, I have to look in multiple places for its artifacts, rather than just nuking .<appname>. And there is no universal pattern of use. It's even worse than /usr vs /opt.
As I don't usually remove programs (or install new ones, for that matter) the scheme that works best for me and many others is "storage/app". In an ideal world a hybrid scheme might be possible, but as it stands now it is not an option and one way has to be chosen over the other.
