It also fits in with their style guide, which talks about writing in a conversational style, https://www.gov.uk/guidance/content-design/writing-for-gov-u...
Yes, their style guide says to use singular "they," and that's what I'm criticizing. Aside from this particular carve-out, it doesn't really align with their style guide, which offers this advise:
* "To keep content understandable, concise and relevant, it should be incisive (friendliness can lead to a lack of precision and unnecessary words)"
* "You should not let caveats dictate unwieldy grammar"
It's perplexing that so many are insisting on creating a problem. There is a perfect solution that affords gender neutrality and incisive language. Why not use it?
