Maybe I'll share my $0.02. Keep in mind that I haven't actively been doing any ASP.Net development, but I have been trying to keep up on all the news. (For my day job, I do Python web development. I'm on the back end team, but have to deal with front-end issues.
In an ideal world, the build process would be as automated as possible. I hit F5, it transpiles my TypeScript, minifies it, and bundles it without me having to mess with anything. At work we've been using Grunt, and I have done a bit of reading about Gulp, and was looking forward to using it. Given that it isn't part of the default project template does make it a lot less likely that I'll be looking into it. I don't have a ton of time to do my hobby development, so the less I deviate from the default project template, the easier it is for me.
In some regards, the current documentation is still pretty scant - I haven't seen a ton of examples of building an entire app from the ground up - back end models using entity framework, showing some basic queries, building controllers, and then making a nice front-end. The reason I think we haven't seen a ton of tutorials like that is because things are still changing at such a rapid pace. If someone wrote a tutorial last week using the basic/starter template, they'd now need to go back and update it. I know that is kind of the nature of software development (constant change), but it is a bit frustrating to try to pick up the new things without some nice solid examples.
