It would be silly to abandon all the work that has already been done, 
and cross-screen development is more important than ever. If you look at 
what they did, it's exactly what you say - they offered the mobile 
platforms as a bonus for professional developers working on the desktop. 
If you're paying your full license, it's also easier to justify 
supporting your specific use-cases/bugs on a mobile platform.

Shaping up on mobile is going to be super difficult. Mobile is on a 
superfast evolution path. Multiple OSes with new APIs (and often new 
look and feel) launched on a yearly base. Qt is on a fixed, 6-12 month 
schedule, and has to abstract away all those APIs into a superset API of 
it's own. This worked on Desktop, as there you got your new OS release 
once in ~5 years, and the changes were still largely cosmetic and 
backwards compatible. However, on mobile, this means that in a *best* 
case scenario, mobile Qt will be 6-12 months late compared to solutions 
primarily targeting mobile (eg Xamarin), and will have to put far more 
resources into it than mobile frameworks as the abstraction/middleware 
is heavier and harder to maintain, with a danger of the APIs evolving in 
really messy ways to be able to cover all supported platforms. This also 
is the reason why the compatibility matrix is so hit-and-miss on mobile, 
and why so little of new APIs are supported until they become de facto 
standards (example: there is no public stable release with a stable BTLE 
API, and the single source promise for full-featured cross-platform 
mobile UIs is turning into a permanent mirage).
