I am glad you asked this question as it was also in my mind.
I spent 3 hours doing the first set of exercise from Chapter 1 of the Minna no Nihongo Honsatsu. I was copying every Kanji/Kana, without stroke order or anything.
I could have done the same in 30 min or less in the computer. While I did learn to write 公社員 (company employee), I could have spend 2,5 hours learning more grammar…
Given my conditions: not a lot of time available, learning for fun/understand when visiting Japan on holidays. I think writing Kanji will take a back seat.
After reading the different points of views. I think it is a useful skill to have. However, very costly time wise and with limited use outside of Japan
Thank you for your question, it helped with my decision.
ありがとうざいます!
