The only advantage I see in maintaining an additional list is improved 
reporting.

Yes, we maintain an XE specific blocklist[*]. This manual effort is 
worthy for someone looking different execution reports. In fact, some 
efforts are going on to develop a platform-specific blocklist.

@kamil, Can you please add some details about upstreaming 
platform-specific blocklist?
