Well this CRC check has only accomplished to stop people who genuinely just want to edit there icons.You cannot possibly state this as fact. It has quite possibly stopped dozens, hundreds, perhaps thousands of malicious users or users otherwise wanting to do something illegal (breaking the license agreement for example). Now, several DLLs are listed in that thread that will help you customise the icons as much as possible, may I suggest following them up?
You can change the mIRC tray icon without DLLs in mIRCs options. Lots of links and information about why the CRC check is in mIRC can be found in
this thread which I assume you've fully read.
I don't see the CRC being removed myself.
