 It autodetects TLS on incoming connections (I'm still wondering why everyone
 doesn't have this), authenticates operators via TLS client certificate
 fingerprints, and supports a number of IRCv3 capabilities.
 
-Not supported:
-
- - server linking (which also means no services); I consider existing protocols
-   for this purpose ugly and tricky to implement correctly; I've also found no
-   use for this feature yet
- - online changes to configuration; the configuration system from 'xC' could
-   be used to implement this feature if needed
- - limits of almost any kind, just connections and mode `+l`
+What it notably doesn't support is online changes to configuration, any limits
+besides the total number of connections and mode `+l`, or server linking
+(which also means no services).
