With proper tools like Caddy or Apache's mod_md, there's no setup needed - they will simply work. Using those traditional free CAs still required getting the signed certs through a sometimes obscure process from their website, transferring it manually to the target system etc. The manual handling alone, which causes work, adds another point of possibly exposing secrets, does not scale, can't be automated, etc was reason enough to replace it with ACME, even if setting it up would be quite complex (which it isn't at all).
