Isn't that true of any function call though ? Any function could end
up deleting this, or trigerring code in another thread, or anything.
For example, a normal function call could end up emiting a signal, and
as such, any function could be as dangerous as a signal.

The other problem with emit, is that it's not required. So its absence
doesn't mean a signal is not being emitted.
