Is cleanfeed still alive and used?

Hi all,
I've been setting up an INN server again, after a 2.5 decade hiatus from usenet. All is well, it works, pulls in news with pullnews. Can't post from the server yet, I'm using accounts on other servers for now.
But, I want to become a part of the larger usenet again (and to be able to post from my own server), so I'm looking at setting up peering at some point. When I look at eternal-september.org, as an example, it requires that I run cleanfeed. But it seems cleanfeed was last updated in 2020.
Is cleanfeed still relevant in 2025? Should I attempt to set it up? In fact, I have it set up, but without recent info to put in its configuration files, I doubt it'll do much good.
Any hints would be appreciated!
Cheers,
Koen
