In the case of water vapor, it is referred to as «negative lapse rate feedback» and demonstrates a net negative feedback cooling effect from increased water vapor. (92.222.7.6)
It's true that changes in the adiabatic lapse rate (which grows closer to the moist adiabat, mainly in the tropics) causes the troposphere to warm faster than it would were it not for the negative lapse rate feedback. (tamino.wordpress.com)
Semantic issues aside, it's probably reasonable to view the assessment of climate sensitivity, as typically done, to entail a Planck («no feedback») response, in combination with feedbacks that include positive water vapor, ice - albedo, and probably cloud feedbacks, and a negative lapse rate feedback.
