Supposedly it is a rootkit detector. The "feature creep" may be due to free rootkit detectors being available? I don't know. Just guessing.
But yeah, on VirusTotal there are so many scanners I never heard of that I refuse to start sending notices my stuff shows as a false positive. Every time I knock one down I'm sure three more will pop up to take its place. It's a time waster. Especially since the person sending in a notice of a red flag in the VirusTotal list is determined to ignore the 45+ green flags. It's so stupid.
