This challenge comes with rewards. Forth has superpowers that can't be found elsewhere.
But its definitely not for everyone. I'd say that the status quo of Forth being an obscur niche is fine, just fine. If you need convincing, if you aren't spontaneously curious about Forth, then it's likely not for you.
I'm in favor of everyone having fun however they want, and you have piqued my interest a bit that it might be fun.
But if even the proponents of the language say that ("needless to say"!) most programmers will be incapable of the challenge of writing good code in it... definitely doesn't sound like anything I'd want in anything I wanted to be maintainable or long-lasting. If this is the outcome you desire, then your, uh, anti-evangelism is working!
I've never written Forth as part of a team. I suppose it's difficult with an average team. But then I try to imagine what a small team of good Forth programmers could do and I'm thinking it would be a quite powerful team.
