We are talking about about user's code. They might have a style guide that 
says that every function need to use trailing return types (for consistency).

They may also want to do stuff like

Q_INVOKABLE auto userName(int userId)
{ return m_users.value(userId).name; }

It's convinient. You might not like the use of auto, but it is not a good 
reason to forbid its use to Qt users. They see this as a limitation of moc.
