Do you have reason to believe they won't be? Are you betting your business on the failure of Apache to do basic release engineering?

That's fair. Because you listed it then I think that's the "major" advantage. Is that right?

Why? Let's Encrypt and HTTPS by default being something that a lot of people want, why do you think Apache will ignore that and not include mod_md in Apache "for a long time"?
Competition is good. I don't have major reasons to be afraid but I would like Caddy/Traefik and others to succeed. From the very basic mistakes they're making in coming up with a business plan, I don't think they will. And no, being open source alone is not reason enough to ensure project survival.
If you re-read your own comment, I think you're the one spreading FUD about those other projects (and their implied inability to outpace Caddy).
