FWIW I have asthma and have been diving about 10 years. I have daily asthma. For me, my asthma comes on slow. If I can't get to an inhaler it often resolves it self in a matter of time. I never get to the point of not being able to breath. For me it's tightness in the chest, but not loud weezing. Since advair I have less issues all together. If I was doing a long dive, that required deco, I know with my asthma if it came on, I could let it pass with out issue. FWIW I have had several dives where o started getting asthma on the surface before a dive, yet knew once I was down it would be gone. For me the dry scuba air helps my asthma for some reason. The other week I had someone smoking at the entry and the second hand smoke was irriating my asthma, as soon as I got down and away from the smoke I was good.
That's not the case for everyone, but with my asthma diving is a non issue. It's a shame any agency would outright eliminate asthmatics from diving all together, since there are so many levels people can have it. Also the level of an attack can vary greatly. Some "attacks" an inhaler puff and they are gone, others gone on there own, while some can hospitalize an asthamtic. So generalizations like no attack in several months can be misleading. I have daily asthma, but never the type that requires immediate inhalir puffs, if I can't get to my inhalor the asthma goes away. Obviously if your asthma is hospitalizing you regularly, or if you are the type that needs an inhalor immediatly, diving is out. Of course a doctor review should always be sought out.
