You may feel it is a kula. Those who issued the psak believe it is halacha. Don’t follow the psak, but don’t belittle the psak by labeling it a kula, which is a not so subtle dig with all its negative connotations
I do not consider calling something a kula a dig, not even subtly. Every kula has its place, it’s to be decided on based on the circumstances. I do not judge anybody negatively if they feel the need to rely on a kula, but recognize it for what it is, so that if and when it’s easy to avoid, you will.
