That 30 chainring is 88% of the 34. So it's like moving everything down one shift.
So you get reasonably close shifts, but in an easier range. This would be very good for a lot of riders. Better than the ultra wide cassettes, like 11-36.

14-32!
A few years ago, I made a 14-32 11 speed! It's a mix of a 14-28 "junior racing cassette" and my 11-32.
Here's the details, and the disadvantages: Custom Rear Cassette for Shimano 105
More details: Building a custom 11-speed shimano cassette?

I only used it to keep up in fast group rides at 18-23 mph, where it had very close shifts. That worked great! Not as practical as an 11-32 for general riding.
