Triumph doesn't care about racing. So they are offering what they think will attract people who like the current supersport class. If they sell enough bikes then, as someone else wisely noted, the racing associations will magically find a way to include the triple. When all is said and done, the bikes that the big4 sell in the showroom aren't the same thing that is racing professionally either. By the time the bikes are modified, tweaked and laoded up with titanium and carbon fiber bits any similarity is purely coincidental. It's always been that way.
