The idea of the new rides was to increase the number of rides people are able to do in a day, spreading the crowds out is a minor secondary benefit on account of each ride's relatively low capacity anyway.
Veering into queue discussion briefly, there's a myriad of reasons that queue times seem just as high/higher than before the new rides came in. The main one being that a higher number of vulnerable people who have had their vaccine and are no longer shielding, so are more likely to visit, so therefore RAP numbers are higher. Add in Fastrack being back in use and a larger number of new staff this year resulting in operations being a tad slower on top of that, and that better explains the difference rather than minor flat rides being unavailable.
