The Naturalization Act of 1790 was repealed by the Founders in 1795:
The Naturalization Act of 1795, Section 4
And be it further enacted, that the Act, intitled, "An act to establish an uniform rule of naturalization," passed the twenty-sixth day of March, one thousand seven hundred and ninety, be, and the same is hereby repealed.
Since the natural born clause was NOT replaced, the evidence would suggest not only that the Founders didn't intend for it to have permanent operation, but that the sole purpose of the 1790 Act was to coincide with the grandfather clause. (Which entitled the Founding generation to the immunities and privileges of natural born citizenship should they choose to become citizens.

What is relevant about the exact wording of the Naturalization Act of 1790 is that the most conservative of judges and legal scholars, who are textualists and originalists are going to look to that actual wording and the context of the Founding generation for guidance as to intent.
To paraphrase: In the beginning, the Founders wanted the children of citizens born overseas to be natural born citizens and not naturalized citizens.
