One reason for these proposals was to put pressure on the SSL certificate ecosystem to provide (CAs) and adopt (hosting) automated SSL renewal practices. Businesses have had three years since Let's Encrypt first went live to adopt such practices, but many chose not to — not just hosting providers, but e.g. bigcorp load balancers too.
Guess what - not all websites are businesses. In fact not all websites are dynamically-generated so why the fsck do we all have to put up with this madness? Make HTTPS/SSL necessary for transactional sites but for simple static sites give me a break.
