Actually, this is agood thing. It's mostly aimed at removing default male language. It's been perfectly standard for years in other fields to make language neutral rather than male - including the also perfectly standard and long established use of 'they' for individuals of unknown sex. I work in a male dominated industry and I'm jolly glad that documents don't refer to 'he' or 'sirs'.
This. I often update docs which refer only to he/him. I correct people on emails who refer to gentlemen and default to male. I may be the only woman in the department, but I will not be made more invisible than they already try, and they need to remember women can do this job, too.
Yes, it should have happened decades ago. But it didn't. If you think it does mean nothing, I suspect you're not working as a minority who is often forgotten. No, I shouldn't have to have that fight any more, either but so it is.
