I think you are underselling yourself. As far as I can tell, at a globally distributed engineering org, clear written communication is probably more important than the code you write, because it has more impact - it has an effect on how everyone else writes their code.
It might come easily to you, but me and other people I know often draft emails and such 3-4 times, asking for proofreading from trusted friends.
Yea, the proofreading for docs and writing client copies isn't fun, but the skills to do these well help all of your written communication immensely.
Your org could be very different, but I feel like I am recognized in large part because I care about communicating, and put a lot of effort into clear emails and docs. Part of your recognition could be because you have great writing skills.
