Seriously. You asked for "an API". Jolla supports the Qt API precisely because
it is a single, high level, app-suitable API that is well managed and open. It
provides a significant degree of platform independence by abstracting a large
amount of platform capability provided by those underlying layers; there is not
much 'limited' about it :)

Not only that it permits us to provide an API usable by C++ and QML/js at a cost
that we can manage.

Having said that, we do need to look to see where there are gaps.

What functionality are you looking for that is not either supported or planned
to be supported by an API exposed by Qt?

If you do want to tinker outside of the store API and enter general linux
programming then you have the freedom to do that too; however Jolla simply does
not have the resources to maintain and/or document all the various systems and
libraries which make up Mer/SailfishOS over and above the various resources that
exist out there on the web (and in the source).
