The tube is now widely used for all London Underground services and
even TfL now use the term for both the deep level 'tube' lines and the
Sub-Surface lines.

So ? Does repetition make something any more true ?

The whole system is known as the tube ergo the met line is part of it
regardless of the loading gauge of the trains. Whether it was considered
so 100 years is irrelevant. Definitions change. Deal.
