KDE doesn’t control what packages are released on a distro? That’s Aurora that chooses not to have point releaes version, and instead seems to have a rolling release from your description.
Bluefin GTS is based on Fedora 40 while Bluefin is based on Fedora 41. Fedora doesn’t do rolling release outside it’s Rawhide rolling dev branch. It does point releases and bug fixes.
There are plenty of KDE based distros that are also point release and not rolling release if that’s your preference. I’d also recommend feeding back to Aurora if you think they should alter there KDE release schedule; they chose when to feed KDE releases into their distro.
Food prices aren’t high; the value of money has fallen - it’s called inflation.
The real problem is wages have not increased so the purchasing power of consumers remains low. So food becomes relatively expensive - consumers have had pay cuts.
