The first two are interesting, but last one you mention is not a lifetime limit, and so doesn't really belong in the discussion.
And the first one is interesting, because that 60 day "limit" is actually 60 days of extra benefits. If those 60 days didn't exist, if Medicare Part A always ended their coverage for an incident at 90 days (which would be perfectly reasonable), then there wouldn't be a lifetime limit, but I think we can safely say that the coverage is better with those 60 days than without them.
Which is to say, you kinda had to reach to come up with examples of lifetime limits.
