Except Unicorn (which I believe to have been there before massive addition), I think the reason Gundam saw an addition is because they signed a distribution deal for Hathaway's Flash, and since HF refers to many events in original UC continuity, people would wanted some background on characters appearing in it (notably Hathaway, and maybe Quess, Amuro & Char).

I didn't subscribe to Netflix so I don't sure what Anime are being offered right now. With the recent deals (HF, Zero's Tea Time), I would have missed/skipped them, even though they are the series I liked. Maybe I will subscribe it once all episodes are shown so that I can watch it and forget it, but I won't subscribe to it long term.
