There are many parts of the world, especially South Asia, where "madam" the default way to address a woman you respect, "sir" is the default way to address a man you respect. It seems to be that proscribing their usage as "unnecessarily gendered language" loses more in cultural sensitivity than it gains in gender sensitivity. This is especially the case because, well, I'm not sure how they're unnecessarily gendered. It would be nice to live in a society that uses genderless honorifics, just like it would be nice to live in a society that uses genderless pronouns... but "madam" and "sir" are as necessary as "she" and "he", at least to people who speak in dialects that favor them.
It is not inclusivity to censor aspects of dialects spoken by people of color. I say that as someone who is not South Asian and who is transgender/nonbinary. This provision of this policy does nothing to make me feel safer as a trans or nonbinary person, and just makes me angry that such cultural insensitivity is being promulgated in the name of my cohort.
