The modern HTTPS world has no place for old web servers.
In practice there are a lot of things that have to be maintained on a HTTPS server. First, you have to renew TLS certificates, or automate it (in practice you've probably had to change how you get TLS certificates several times). Even with automated renewals, Let's Encrypt has changed their protocol once already, deprecating old clients and thus old configurations, and will probably do that again someday. And now you have to keep reasonably up to date with web server software, TLS libraries, and TLS configurations on an ongoing basis, because I doubt that the deprecation of everything before TLS 1.2 will be the last such deprecation.
