The rejections themselves will be received by the mailing list (assuming RFC-conforming recipients), so I think this is unlikely in theory. I haven't heard of this happening, and Mark says he hasn't either. The failure notices received by DMARC senders are another matter. These are not supposed to be used for blacklisting, but as we already know, Yahoo! and AOL are desperate. OTOH, they're already known to be hostile to mailing lists; getting blacklisted by them is not news. I suppose we could worry that they would publish their blacklists to be used by others, but it was pointed out to me by Murray Kucherawy that MAPS was shut down by lawsuits, and it seems likely that a public whitelist or blacklist would attract them too. My estimate is that this is not something to worry about because it will be mitigated by any of the options already implemented, and it's not something to complain about because there's no evidence it actually happens. IMO, we need to avoid crying wolf; there are way too many people (including a number of Mailman list operators) with a vested interest in painting Yahoo! and AOL as well-intentioned but overwhelmed by circumstances beyond their control.
