I can’t say that I’d choose any of the three options – encourage, discourage, or ignore – but I can’t think of another option. I wouldn’t want to encourage, because that creates a feeling that it would be expected, and what of the people who don’t care to, it would just be something to make them feel inadequate. As to discouraging, well, I don’t think forcing it into the shadows would be good for those who suffer from exploitation. And ignoring it? Doesn’t seem like an appropriate option, either. Could we settle for not not-discussing it? Not making it taboo? This is probably why I’m not professor material…
