After the (temporary) defederation announcement of earlier i checked the Lemmy repo to see if there was already a ticket on the federation limiting option like Mastodon's that people mentioned Lemmy doesn't yet have. Not only i didn't find it, i also saw that there's about 200+ open tickets of variable importance. Also saw that it's maintained mostly by the two main devs, the difference in commits between them and even the next contributors is vast. This is normal and in other circumstances it'd grow organically, but considering the huge influx of users lately, which will likely take months to slow down, they just don't have the same time to invest on this, and many things risk being neglected.
I'm a sysadmin, haven't coded anything big in at least a decade and a half beyond small helper scripts in Bash or Python, and haven't ever touched Rust, so can't help there, but maybe some of you Rust aficionados can give some time to help essentially all of Lemmy.
The same can be said of Kbin of course, although that's PHP, and there is exacerbated by it being just the single dev.
It's really the best language right now for a lot of things. It's not easy to learn but once you start to get parts of it, it's a great feeling.
It's sadly complicated and that's the only problem with it. If it was less complex it would take over everything because it's just so much better.
Unfortunately the complexity is what makes it so good. I don't know how you could make it simpler but remain just as powerful
