As a secondary data point, the last time I profiled eds-dbus sending
thousands of contacts over the bus, message validation (specifically
UTF-8 validation) was something like 20% of the runtime.

Amusingly I attempted to switch the transport to arrays of bytes to skip
the validation, but the array validation was actually even slower...
