For this purpose, since we're talking about what kind of compiler and language
features will be allowed in the source code, we have to be very broad. For
example, suppose we want to allow template-template parameters in the code
without restrictions. That means TTPs may enter into our API.
Now imagine someone wants to port Qt to a platform with a compiler that
doesn't support TTPs. That will be impossible because TTPs are mandatory and
cannot be worked around. So this port is dead before it even starts happening.
This is why I'm recommending being very conservative. Once we allow a feature
unrestrictedly and it enters the API, there's no going back.
