Most of it is likely a waste of time. The market (if it is as capable as it is lauded to be) will look at who is likely to be the last to ‘walk away’. If the government is that last one able to walk away the ultimate risk will be on them.
This ties in well with the ‘used car’ problem of university graduates and degree classifications.
Even then it would bind not only future administrations and but future congresses. That would mean and effective end to sovereignty, at least in this area, of the federal government.
