Ignoring the fact that the "world's first" claim is untrue, do you remember when a "world's first" at Towers actually meant something, i.e., an advancement in roller coaster technology?
Do you not think that is a worldwide industry trend, though? From the late 1980s it was all about things being taller and faster - but those days are largely gone because few parks have the will and financial resources to chase those. Plus, regional parks that chased those records have often regretted it, being left with maintenance nightmares in the form of Kingda Ka, Dragster etc.
Also, I think the perception around records has changed. Colossus having 10 inversions in 2002, almost felt more impressive than 14 on Smiler a decade later, but I think that is generally down to a lot of apathy in the community because big rides are so much more common now, than they were then.
Therefore, you do end up with more tenuous records and world firsts. There are only a certain number of ways a car can go around a track so you end up with dumb world firsts or quite literally adding half a degree to the steepness of a hill. To their credit Merlin have done some unique/new projects like Ghost Train, Raptor etc, with varying levels of success, I grant.
It feels like the approach here has been to create a fun, marketable ride and then attach a world's first statement to it to help with the hype. People can bemoan the fact that they are marketing it with that label, but the ride itself is unaffected.
I've been excited about this since the start, very much looking forward to it after the announcement.
