Can Gutenberg be used as an editor on a page?

As Tammy states here:

There is a plugin you may want to dig a little into
https://github.com/tomjn/Frontenberg, this is purely a demonstration
of putting Gutenberg on the front, not something that is planned yet.
It may hold some insights though for you. Right now there is no
option/shortcode to do this.

That was written a year and a half ago, so many things have changed. It may be simpler now.
