This is probably to compete with Halon gas in data centers, where you can't use sprinklers at all . . .
I've worked on many small data centers / server rooms ranging from 5,000 to 200,000 square feet, designing HVAC and plumbing mostly, but also a little fire protection, and all of them had pre-action sprinkler systems, as back-up to gaseous fire suppression systems or as the only fire suppression system. Water-based sprinkler systems were often required by codes, including, surprisingly to me, in an emergency generator building that housed six 3 Megawatt diesel generators operating at 4160 Volts originally designed with a CO2 fire suppression system. (just have to hope not being in that space when the sprinklers go off if the generators are running)
