There is usually some clause in the statehood grant that indicates this. I know this is the case here in CO, however, there is ALSO a clause that gives FedGov access and, unfortunately, jurisdiction, at least, on public lands.
I don't think it would make any difference if there were. While I sympathize somewhat with the argument, I know that no court is going to agree with it. See Unites States v. Texas (1950).
Specifically:
(e) The "equal footing" clause prevents extension of the sovereignty of a State into the domain of political and sovereign power Page 339 U. S. 708 of the United States from which the other States have been excluded, just as it prevents a contraction of sovereignty which would reduce inequality among the States. Pp. 339 U. S. 719-720.
If I'm reading that correctly it doesn't matter what kind of deal a state makes when it joins the union. Once it's in the union its rights are the same as any other state.
Aside: when I was young I used to think the label "indian giver" was supposed to be a slur against the Indians.
