It's absolutely been worse here lately. I don't know that I'd call it worse than reddit, but Lemmy is definitely trending more toxic. I'm certainly not a heavy user by any means. Idk if the more reasonable voices have just become less active or if more toxic voices have arrived or what, but where as 6+ months ago things tended to be more discussion prone than antagonistic, it's now mostly antagonistic, especially in the more popular communities.
I will say, I've left many of the lemmy.ml communities in favor of similar communities on other servers and that's helped as far as making my feed of posts less toxic to boot (and less spammy).
I haven't done much of my own moderation in blocking so I'm running mostly based on the server moderation.
For what its worth, many package managers support some method of exporting a list of installed packages to a file (or in a way that can be easily piped to a file), and its not difficult to pipe a file of packages into a shell loop to get the behavior as described.
Native support in the package manager would be nice, sure, but the Unix philosophy of providing tools that can easily augment each other to solve problems means this is generally a trivial thing to implement by anyone in a way that works best for their use case.
