Are there plans on adding something like spawnProcessDetached that would

On Posix that could be done via double fork technique. Not sure about
Windows.
Double fork on Posix is, usually, used for something slightly
different. In particular, since you bring up the process group, I
think you mean daemonization.
Daemonization, however, does a bit more than create a new process
group and double forking.
http://forum.dlang.org/thread/[email protected] has
discussion and some code regarding this issue.

It's not about daemonization only. Different process group is needed to
prevent signal distribution. Again, e.g. file manager and launched
application may want to not be connected in any way.
Yes, that's part of daemonization. So is chdir somewhere else and
closing all open file descriptors, including stdin/out/err.
