The 2020 part isn't really something I chose, it comes with the SwiftLaTeX engine, which ships a precompiled format from that era. I just inherited it with the engine.
The format and packages have to agree, and when I pulled in newer packages against that old format, some things broke (hyperref had changed its aux label format, for which I ended up backporting a padding fix, and babel was missing some aliases in the mismatched version, e.g. brazil-portuges).
And yes, I'd be very happy to help with that and will get in touch via the volunteers page!
