Well to be fair molotovs should be buffed through accessibility imo. I also liked the suggestion of them dealing 40 damage initially and then do damage over time. Soviets are clearly showing their age. They have been the same since beta when the game was almost completely different. Cons should get molotovs by default when t1 or t2 is built in their current state.
Upgrades shouldn't be removed and given out freely for teching up since it does remove player choice and alternative play styles. The Molotov should be adjust to a viable upgrade for what it costs. That way player choice is kept and more viable strategies can evolve (e.g. do I go for molotovs to try and bolster my early game to get a better share of the map or do I try to rush a vehilce?).
One of the reasons why people say coh1 had more depth in certain aspects is because for instance USF had a lot of upgrades (nades, stickies, bars (global upgrade), demos, supply yard upgrades). The timing or if you planned to use them was up to the player and led to more viable strategies (rushing nades, going for bars or a fast m8 etc.).
