To quote from the Slack engineering report

> This indicated there was likely a problem with the ‘*.slack.com’ wildcard record since we didn’t have a wildcard record in any of the other domains where we had rolled out DNSSEC on

I'm not going to stick my hand in either camp for the sake of this discussion, but dynamic/wildcard DNS records are exactly the type of thing I'd suspect DNSSEC to have trouble with

I, on the other hand, can speak from experience, and I say that where I work we currently have over 100 domains with DNSSEC and a wildcard record, and they all work just fine.

I wasn't implying that wildcard records are something entirely incompatible with DNSSEC, more that certain nameserver implementations could potentially have trouble with them.
