+1 totally agree!
@Neilpang thanks for your hard work and early heads up of this change.
I've been using acme.sh for my underlying Centmin Mod LEMP stack integration to automate HTTPS/SSL certs for Nginx vhost site creation for years now and tens of thousands of Centmin Mod users have automatic Nginx HTTPS because of acme.sh 
Certbot/python was just too heavy a footprint compared to pure bash script.
Example of how Centmin Mod LEMP stack uses acme.sh and Letsencrypt to automate Wordpress installation with advanced guest full HTML page caching and HTTPS by default with CF DNS API based domain validation & configuring Cloudflare Full SSL and Nginx origin configured with optional dual SSL support for RSA + ECDSA SSL Letsencrypt certificates https://blog.centminmod.com/2020/09/06/203/wordpress-cache-enabler-advanced-full-page-caching-guide/
