In practice the cadence is exactly half that of WG21's breakneck C++ pace. Every six years. C11, C17, C23 so far and C2y is expected to land before the end of this decade.
But anyway, all I can do is report the observable fact. If you want to say it's because GCC 15 is a different product from GCC 4 whereas rustc 1.99 is the same product as rustc 1.49 then I guess you can re-phrase my position as "In C you will keep needing new products and that sucks" if you like.
