I actually just migrated a small Rust application to C++ with Qt because I have to use DBus and Qt has a very nice DBus library, which Rust has not. (In general, DBus hates runtime environments that don't have an event loop.)

It's pretty hard to have asynchronous calls without an event loop ;)
Using DBus synchronously is, strictly speaking, wrong unless you can PROVE that there can be no deadlocks; talking to the DBus daemon itself synchronously is generally safe though. Unfortunately QtDBus encourages synchronous calls. Maybe you remember desktop hangs in early KDE 4 related to global shortcuts - that was me not knowing that rule at the time.
