A guy I used to work with in a barely heated darkroom with no running hot water would routinely add hot coffee to the D76 to bring his developer up to temperature.
The trouble with wet film comes when it dries out.
If its rolled like in a 35mm canister with nothing in between the rolls of film it would stick together. If I dropped exposed 35mm or 120 film in the lake or (more likely) it got dunked in the water in my ice chest - where I store it in zip locks while traveling in the summer. I would try to keep it wet until I could get it on a reel and into the developer.
Thinking about it, that would be the best way to dry it out - put it on a developing reel and the let it hang out in a dry developing tank until dry. Then you would have to move it to another light tight storage.
