One can still create style instances using QStyleFactory::create(), so I don't see any reason to remove this API. The -style <key> command line argument keeps working as well.

Since Thiago +1'd, I think I'm good...so I've posted the bug to Jira for it per

But this is totally orthogonal to the application being a daemon/service. To 
some daemons your application "talks" HTTP, SMTP, mysql-protocol or whatever 
others...
Why would someone writing a cron-alike daemon want to listen on some 
QLocalSocket?

That is the task of:
- launchctl on Mac
- Service-Manager / "net start" / ServiceControlManager-API on Windows
- Init-Scripts (or interfaces to them) on Linux
  [This describtion meats OpenRC, Upstart, systemd and even SysVInit, right?]

Without using those, you blindly bypass any security mechanisms that the OS 
itself provides for services/daemons.
I really wouldn't like anybody on my system capable of creating a QLocalSocket 
to also be able to stop a service.

> Thus, some inter-process communication is always required.
IPC can also be shared-memory or files on disk. This has nothing to do with a 
QLocalSocket.
