If the market is large enough, there will always be a plugin developer who is willing to cater to that market. I don't see an option for the classic editor or something like it going away anytime soon.

But, Gutenberg is much larger than just the editor, which is something to keep in mind. It is and will continue being a complete re-imagining of WordPress in the coming years. The editor was just Phase 1. Even if you have an alternative editor, you won't completely escape Gutenberg without having an entirely different admin interface.
