CVE-2022-26491: Remove _xmppconnect DNS method from XEP-0156 and add warnings by moparisthebest · Pull Request #1158 · xsf/xeps
An issue was discovered in Pidgin before 2.14.9. A remote attacker who can spoof DNS responses can redirect a client connection to a malicious server. The client will perform TLS certificate verification of the malicious domain name instead of the original XMPP service domain, allowing the attacker to take over control over the XMPP connection and to obtain user credentials and all communication content. This is similar to CVE-2022-24968.

Yes, this way is even better, given that as of now, https and wss are effectively the only schemes that should be supported, as bosh and websockets are the only alternative connection methods you can discover with the XEP.
Only other nit:
The markdownish or doesn’t really fit here. We have <em>or</em> or <strong>or</strong> for this. :)
