Austin Kleon puts this especially well in “Steal Like An Artist.” He says that you can cut off some of your passions, and try to focus on one thing, but eventually you will “feel the pain of the phantom limb.”
Now, given the vast population of the world, I'm sure there are a few people out there who are into bluegrass-rap fusion, but your friends, family and neighbors are probably not going to get much out of it.
So who do you want to make art for? Who do you want making art for you? Random strangers peicing together art from fragments of digital audio they stumble across while surfing on an endless stream of information?
The answer is not different, it is the same for EVERYONE! Turn around and swim back to land!

Without any examples for or to the contrary, I'm not convinced this is true.

I think both extremes are harmful. But my experience comes from dabbling in Jazz music of all sorts; 'Jazz fusion' is such a broad moniker that it extends from funk to rock to swing to rap.
There are two volumes of Songwriters on Songwriting and I guess I could introduce you to all my songwriting buddies if you're so inclined.
When it comes time to settle down on a voice and hone your craft, sure, I would never recommend you switch up your style for the hell of it. But if you want to read widely, and if doing so refines your style, great. Go for it. It probably will.
Again, the way the author characterizes this 'problem' is jarringly foreign and antithetical to my own experience. Perhaps I lack the objectivity to see it the way the author does.
Perhaps an analogy to songwriting will make things more clear: how well received are the works of someone who writes rap-funk-metal-folk-electro-bluegrass songs?
