There's a number of problems with this.
It would only work if enough communities and instances adhered rigidly to similar editorial decisions about what is "political". I don't think that's achievable.
Mods would have to do the heavy lifting in tagging/ untangling things.
It's not going to be as simple to implement as you think.
Posts are already categorised by community. You can block the vast majority of political posts by blocking a few communities and users.
At times if filtered out keywords like Musk and Trump. You don't really need to implement a feature for this. Just get posters to include a tag in the title of their post.
Looking at your other comments, you're not going to be deterred by these criticisms, so my suggestion would be to find the git repo and create an issue to get some proper feedback from other contributors.
Congrats to the new admins!
As regards instant recall, I'm new here (but not new to lemmy and the broader fediverse) and don't feel I have much of a voice regarding how things are run. I also don't have much experience with the concepts of anarchism and the idea of instant recall is new to me, but I do have a lot of experience in governance for large organisations.
That said, I have some concerns.
Primarily, I can't see how including yourself can work in practice. Even if 70% of voters decide that your actions are contrary to the desires of the instance, you will be confident that your own actions are necessary and justified (otherwise you wouldn't have taken those actions). You've already acknowledged that you're a foul play failsafe. So I guess I'm saying, from your perspective any motion to recall your mandate is very likely to appear to be foul play.
Sadly, I'm conditioned to suggest having a robust code of conduct and a committee to refer breaches to, but I suspect that is not the way of anarchism.
Regardless, I'm very happy to support this instance and look forward to seeing where you take it.
