Any additional comments?

in version 3.2.44, v-model generate ref assignment code for setup-reactive-const bindings, this commit changed it

I think generating ref assignment code for setup-reactive-const bindings is right, just like const a = ref(1) ("a": "setup-ref"), and it maybe an object in reactive like const whatever = reactive([]);

so v-model should generate ref assignment code for setup-reactive-const bindings

You should use ref for a primitive value

this commit is a fix for #6241, and it's the correct, intended behavior. as @sxzz correctly says: to reassign a "variable" with v-model, use a ref.

[baohangxing]

the primitive value here is just a example

see this =>
to reassign an array with v-model, like
this example @sxzz @LinusBorg

thanks

Again: for that, we need to use a ref()
