So Russia will tax utterly destroyed land where no economic activity can happen for another generation? And Yeah, sounds like a great plan.
Moreover, they are essentially gaining maybe a couple 100 sq miles per year. In that rate they will take 50 years to even get to Dnieper river, let alone crossing it and then taking over central/western ukraine.
By Russian and neutral mapping, they gained around 2500 square kilometers last year. In some months they were gaining around 500-600 sq.km. The Ukrainians have a different mapping and they mostly tend to mark things as grey zone. They only admitted to the loss of Pokrovsk over six months after Russian units raised flags all over the city and neutral mappers already called it. This year it appears slower and that's because Ukraine no longer has this Kursk offensive as an overhang which sucks and bled their forces.
Personally I believe they will settle when Zelensky's demands to freeze conflict on the contact line crosses with Russian position for Ukraine to give up the Donbass into an intersection. Meaning when those two requirements are one and the same. That is, the fall of the entire Donbass. This also means the Russians will take extra territory in Sumy, Kharkhiv and other regions as buffers.
With Konstantinovka now literally doomed day by day, this leaves you with Dobropillia in the Center Group, Druzkivka-Kramatorsk-Slavansk in the South Group. All these urban settlements are now in FPV drone range and artillery ranges, with outskirts within indirect tank fire range. Liman is falling just as quick, which means the Russians can also approach Slavyansk from the north, and there's many forests in the area where Russian infiltration groups can insert themselves. As I said before, and will say again, forest and urban fighting is mano-o-mano fragfest. Just boots, guns, and skill. The side with the numbers and retaining the most skilled and experienced fighters will take it here.
Personally I also believe the war may end before the end of Trump's term. It's very likely at this point, a Democrat president maybe elected next, and Putin's best chances of ending the war lays best within Trump's term.
