It does make it a federal matter in that now, the federal government recognizes it as a right, thus, violating the Constitutional protections of, for example due process. In other words, the Federal Government recognizes the right of an individual's life to be taken without due process. You are correct, it shouldn't be, however, the reality is it is and thus, in partiality, it must be dealt with as such. To just say 'leave it up to the states' gives an implication that State's rights (or that of any government entity) supersedes individual rights.
So get Roe overturned, return it to the states, and then work within the states (and maybe, decades from now, an amendment).
