Exactly. W-2 and 1099 income is really straight-forward. If anything the IRS should provide ways for you to submit all your non-W2/non-1099 income to them and roll them up into a new form so that no matter what your situation you can "fetch" your current returns, sign them, and submit them. No need for third-parties at all. Any additional complexity is a symptom of rent-seeking IMO.
