I wouldn't really think of this as a retcon. It's not like his sexuality was ever made a plot point in the books; it would only come off as a "retcon" to a reader having assumed he was straight or "asexual" or whatever else (despite the books never saying anything one way or the other). This would be like suggesting it would be a "retcon" for a Disney character to be revealed to be very much heterosexual, just because the movie they were featured in never indicated they had any sexual inclinations whatsoever.

I wouldn't usually consider something a retcon unless it's some new piece of information that completely flies in the face of previously established information. Key word being established, not just inferred.

Here's something to think about: would anyone be calling this a retcon if JKR revealed that Dumbledore was straight instead? Somehow, I doubt it.
