Hi. Progressive Enhancement is a separate term and concept from Progressive Web Apps. The intention is not to replace the meaning of Progressive Enhancement. As you say, it is a very important concept in its own right.
Progressive Enhancement is an important aspect of PWAs, as it is for web development in general. PWAs are bringing new features to the Web, but it should/must be done in a way that does not break the experience for anyone else. I guess that's why Alex chose that word in particular.
