Assuming Auntie Beeb gives a rat's arse about this particular concern, keep in mind this could also give RTD or anyone else leeway to "fix" the problem by giving Jack (or another character) another male lover, or having a same-sex female relationship in the next series.

Making the argument about homophobia a focal point, doesn't necessarily bring back Ianto, or an idealized Jack/Ianto.

It's also unseemly as others have pointed out, to do so in a document that teems with misogyny and heterophobia. As virulent as the Gwen-hate is in that next of the wood, they really should have gotten at least one outside pair of eyes to look at it. Someone not as invested in their POV might have blown some sanity into the discussion.
