If it doesn't then the code you wrote yourself will eventually break as the rest of the world advances their APIs and standards.
Even a website written in pure HTML and put up on a small linux server a decade ago would have rendering issues as well as probably not allowed past browsers or corporate firewalls due to older SSL libraries.
Unfortunately the only apps that live in a vacuum are embedded apps not connected to the internet. We should all be monitoring our dependencies for security upgrades. Eventually even a stable framework like Django goes out of long term support. I wrote a Django app in 2008 that is still in heavy use today and at some point had to go through and upgrade to a new major version. It wasn’t a breeze, it took me a few weeks. To leave the app live on that 10 year old version would have been irresponsible for security reasons. The only apps that live in a vacuum are embedded apps, like the one in a vacuum cleaner.
It's so old it has no https interface.
I do depend on my hosting provider to keep Apache and FreeBSD up to date, if only for security reasons.
