That's pretty much true of any django release... you can stay on it if you so choose to. It will get security updates/bug fixes for a bit and then they will stop coming. You're free to stay where you are if you want.
It turns out that most developers have a desire to move to the next version if it's not too hard. There's still COBOL programmers out there too and that's perfectly fine.
Django has made the process as smooth as it can be. You can upgrade to python3 while maintaining your Django version. Then update to the next Django version as a separate step. It's fine to have waited until now. You can keep waiting if you want but it's getting to the point where you should really just do it. It's not so bad.
We switched and python2 --> python3 was bumpier and more work than most Django updates we've done (we've done pretty much every one since 1.0) but it was still entirely reasonable. We're much happier now.
