That's not entirely true. Most of the communication with the telepathy
infrastructure is done through some C++ QML wrappers and with the help of
some C++ daemons.
The code for this is all in this branch:

Most of the code you see in the QML is to provide the UI representing the
current state of the telepathy accounts, but  there is always the need to
invoke the C++ code from the QML, and that's basically what you see there.
Of course there might be places where this could have been better divided,
so if you have suggestions and/or patches, we would be glad to review and
apply them.

The API that is there today is already C++, but mostly meant to be used
from the QML side. It is not declared public yet (we are still finishing
implementing all the required telephony features), but I think at some
point it will, just not sure when this is going to happen.

That depends on what you are trying to achieve. If you want to add support
for a new service/protocol, that's probably the way to go, but if you want
to write a different UI for the telephony stack, you can probably reuse the
QML bindings we already have, but just be aware that as they are not
declared as public APIs yet, they are very likely to change in the future.

If you need help understanding how all of this is implemented in Ubuntu
Touch, you can find me and Tiago on the Ubuntu Touch IRC channels on
freenode (I'm boiko on #ubuntu-touch and #ubuntu-app-devel)
