Rubbish. The dome supports the structure of the glass: you see the same thing in wine bottles. The capacity of the glass has to be what it's labelled or sold as.

In wine bottles the dome makes sense, there's high pressure during corking and it helps with holding back potential sediment while pouring.

There are lots of reasons for the punt and many apply to open containers. It makes a vessel more stable on a flat surface.
