What is the purpose of =thread-created? Presumably, this is to allow
the frontend to keep up-to-date list of threads without doing -thread-info.
For that to be possible, it's necessary that for every single thread in
the output of -thread-info, there's also =thread-created.

Of course, a frontend might decide to use -thread-info most of the time,
and use =thread-create to update the list only when the target is running,
in which case reporting the main thread might be less critical. But still,
it seems more consistent to report main thread, as long as -thread-info
includes it.
