Polling I saw not too long ago suggests reasons why there are some sticking points on the deal:

Tuesday, 25 March 2025, 13:38
"Details: Regarding what constitutes victory, 30% of those who believe in Ukraine’s success consider only the complete expulsion of Russian forces and the restoration of borders as of January 2014 to be a true victory.
For 17%, victory means the complete devastation of the Russian Armed Forces and the incitement of an uprising or the collapse of Russia.
A further 22% would consider victory to be the restoration of the status quo as of 23 February 2022, while 11% would see it as the expulsion of Russian troops from all Ukrainian territory except occupied Crimea.
For 10%, the end of the war would be considered a victory, even if Russian forces remain in the territories seized after 24 February 2022."
Elections would be coming shortly thereafter, presumably. It was forecast that there will be heavy meddling, but here is the recent poll I saw.
List of personages was for polling purposes only and not a list of candidates afaik

The point is that even if the torches and pitchforks did not come out over a harsh deal, the political situation is unlikely to allow for the current offer because it's almost certain to politically destroy a harsh deal signatory and probably the other parties nearby. That's a notable thought, because would the political backlash open a gap for a pro-Putin candidate? I doubt it, but it seems like the disruptive sort that would help with that effort.
