no it's not a problem it's just syntax sugar.

Describe the solution you'd like
I feel like I'm actually using fetch when making a POST request.

For example right now my POST request looks like this:

const { data, error, doFetch, isFetching } = useFetchp('GET', 'localhost:3050/api/auth/v1/register')

doFetch({
	body: JSON.stringify({
		email: 'info@ssibrahimbas.com',
	}),
})

I think we can do it this way:

const { data, error, doFetch, isFetching } = useFetchp('GET', 'localhost:3050/api/auth/v1/register')

doFetch({
	email: 'info@ssibrahimbas.com',
})
