I doubt devs are "ashamed" of making js web apps. The main issue is that it takes more effort to do so than a traditional web app. There are browser specific quirks. Frameworks like rails are so well-integrated with the db layer that it will be difficult to match that productivity with pure JS apps. And finally, a lot of devs don't want to take the time to learn, when the current standard is perfectly acceptable for most use cases.
