Hi, we are examining the Special:RecentChanges process at this time, but RC is a very technically expensive process. While we want to support loading as many items at a time for users, there has to be some sanity limit somewhere. So while the ticket about improving page loads for thousands of RC entries is still being examined, I honestly can't anticipate much movement on the current behaviour.
