Little Snitch definitely needs a social feature where you can crowdsource good rules from other people and see what rules are common within the communities for certain apps.
I subscribe to rule groups through hostblocker.app, which pulls HOSTS files from different known websites and compile them into a .lsrules file which Little Snitch can use.
While I cannot vouch for the website's underlying code-I did not write it and I can not find an open source implementation-It only provides rules and I can edit any rule group to my liking after subscribing to it.
If you allowed crowdsourced rules, someone could sneak in a rule that says to allow their random app to connect to a random host, which is how malware exfiltrates your private data.
