Agree. Svelte is a blast to write as an old grumpy backend engineer. But yes, probably just scared for nothing. Turning onMount() into $effect() is a tiny change, but this self-aware smol brained grug likes onMount() as it means something! To enable logical grouping, Svelte 5 allows us to nest the $effect()s? What does that even mean? Where am I? Nurse!

nesting means that a variable being watched in the parent scope triggers both the parent and child functions, but a change to a variable in the child's scope only triggers the child function.

maybe super specific to this comment but onMount isn't going away, it could be replaced with $effect from an implementation standpoint, but it would be wildly confusing if used for that purpose without the clearer name for the wrapper
