[Just mythoughts]

What did her being turned into salt have to do with sodomy? Not much. What is salt? It’s inorganic; it doesn’t change; you can “dissolve” it in water, or mix it into something, it still remains unchanged, as salt. Lot’s wife did not long for sodomy. She longed for the lifestyle Lot was able to provide for her. She was not wanting and willing to head out into a future with no guarantees. G-d had a deeper purpose for Lot and his family and change was the first part of that. “Looking back” is failing to change, failing to accept change, failing to be allow yourself to be led by G-d into an unknown future. That’s why Lot’s wife was turned into “salt” (as opposed to being turned into something else) - for desiring to remain fixed and unchanged, even when G-d’s will seeks that change for you.

Ah God gave her a way out of Sodomy to 'live', but she was NOT willing to live... because she did not heed the warning... God was going to destroy the heap and yet for whatever purpose He had planned, gave this woman the opportunity to be saved and she for whatever excuse looked back at 'home' longingly... Now it is most curious that Christ took the time to remind any who will to 'remember Lot's wife'.

“because she did not heed the warning... “

It was not “G-ds warning ‘about the destruction’ it was G-d’s warning “to not look back”.

The warning and its purpose would have applied (in the spirit applies) to any circumstance for which it was/could have been/is given. The specific lesson to lot and his family WAS a “warning to not look back”; to not hold on to the comfort of a life you have when G-d is leading your life through change.
