I know for a fact that at least one of those certs was replaced with a DV cert - once the team in question had to replace it, they realized there was no point in replacing it with an EV since the browsers are removing the EV UI anyway.[0] I'd bet that a meaningful proportion of the certs in question are similarly being replaced with DV.
