That would work for keeping the click-handling internal to Pidgin/libpurple.
You'd still not easily have the reference information like which
session or conversation the link was clicked in.
For MXit we'd still need to encode that data in the URL.
  eg, mxitlink://account-name|connection-name|who|link-data

But it's still a cleaner solution than overriding PurpleNotifyUiOps.
