Yes. Height is not a primary sex characteristic. People do not look at a 5'8 man as more feminine than a 5'10 man. If a man views himself as needing to be taller to be a man there is something else going on and its not gender dysphoira.

You seem to consider gender affirming care to be anything that increases confidence. Buying a cool jacket would be gender affirming care to you. I hate this because it waters down the topic to pointlessness. The world health organisation definition of the word includes "when it conflicts with the gender they were assigned at birth" which I agree is nessesary.
