> One thing I don't like about Git LFS is that there is no way to delete very old history. It's the 'git spirit' to not allow deleting history, but in the context of LFS it sounds horrible. Especially if you use Github.

At my dayjob we used Git LFS for a bit, but foud it unworkably clunky - we eventually found it easier to just make a separate "LFS" repository and add it as a submodule to the main monorepo. Now we can rewrite the history of the LFS repo on an as-needed basis.

That's one of the features of Git LFS is separately managed storage and lifetime.

You are correct that GitHub does not offer that feature.

Git LFS is unusually bad. I think the maintainers are trying their best but it is one of those things where there are so many bugs and so many users that they will claim they are overwhelmed with LLM authored PRs instead of conceding that they own a very valuable piece of real estate (being installed alongside git by default) and totally mismanaging it.
