I wouldn't say so.

1): Gale of the Hurricane truly is one of the best Tuners in the game and can be splashed in many decks (albeit its Special Summon effect only works for Black Feather Decks). Its ATK and DEF reducing effect is a treasure; it is a once-per-turn effect. Of course, after it is used the first time, it will most likely be used for an immediate Synchro Summon. I won't be surprised if this card happens to be Semi-Limited in September (but of course, we still have the Bolt Hedgehog Unlimited as well).

2): I won't suggest that the individual Black Feathers (except maybe Gale) will ever be Semi-Limited or above. But they are indeed monsters whose effects are above average, especially in the competive enviromment.
Shura- can swarm the field with Black Feathers (1500 ATK or below, which also includes the afformented Gale, good especially with Urgent Tuning), 1800 ATK (just 100 ATK away from really being considered "broken").
Lance- Special Summon effect akin to Gale's, Piercer, 1700 ATK (well, it's better than most of the piercers in the game).
Sirocco- Normal Summon effect akin to Big Piece Golem; additional effect supplements a Magician's Cross-akin ATK-boosting, "only it can attack" effect. The best part of this card is that the majority of BFS can be Special Summoned when this card is already in play, including Gale (the tuner and Shrink user) and Lance (the defense piercer).

3): Indeed being DARK makes Black Feathers subjected to Crush Card Virus (especially Vayu, who can be used for Cemetery Synchro). However, the very fact Crush Card Virus is limited (just like its buddies Emergency Teleport and Dark Armed Dragon) doesn't make this strategy a guarantee. Foehn is indeed a powerful card, especially if you use and reuse Qa'lat of the Moonlight. Then, you will have a 1900 ATK direct attacker (as well as its effect to switch an opponent's monster in face-up Defense Position, which supplements Bora the Black Spear and/or Black Feather- Arms Wing).

4): Just because a certain deck is great competively does not ensure that it will be crippled right after. Lightsworns are still use competively, with only a few of its cards ever Semi-Limited or above, and a few cards made to counter them (Deck Dimensional Weapon and Core Chimair Drago). I would be more concerned about the Core Chimair being used competively; we're bound to see a lot more in Ancient Prophecy and Stardust Overdrive (assuming that the set is not a false April Fools' Day trick).
