A quick look at maemo.org/downloads[1] doesn't support such conclusions for community projects. As for commercial developers, keeping in mind that Nokia actively discouraged Maemo 5 development even after Qt became mainstream on it, I wouldn't expect much until other manufacturers produce MeeGo products. Ones that are not pronounced dead on arrival.

• 770: 253 packages

• N900: 658 packages
  
  Note that the vast majority of these are Hildon apps, ie not portable to Harmattan
