You're not wrong. I'm saying what I interpreted from their filing and mnunchin and calabria's words.
There is no way anybody can interpret the filing to mean that Treasury would neither convert the seniors to commons nor exercise the warrants.
Trump's letter said he would have sold Treasury's common stock. Converting the seniors to commons and exercising the warrants are the only ways Treasury could acquire that common stock. (And no, those are not mutually exclusive. Treasury could easily do both.)
So if you're going to make arguments based on that filing, you must support either a senior-to-common conversion or warrant exercise.
Arguing for warrant cancellation, as a common shareholder, is completely self-defeating considering the alternative.
