I disagree, it is a consequence of debt outpacing growth.
The key characteristics of a reserve currency are stability and liquidity. If you have these, you don't even need to pay interest.
With properly managed that, being the reserve currency is a win on all fronts. You get to run a deficit because people are happy to trade real products for your paper. People are also willing to loan your paper back to you at more favorable rates. The only downside is if you get drunk and outspend even the inflated demand for your currency. The smart move is to rain in deficit spending if you can't get favorable lending rates.
Blowing up reserve status doesn't help this problem. Then you just have to pay higher and higher interest rates because no one wants your paper anymore
