AFAIK VHD and similar formats do not save data if it's not allocated in the MFT (or whatever table corresponds to the formatting of the partition).

That's not a plus, but a limitation of SSDs, which need to zero out every page/cluster before using it again. Using trim in the background speeds up the process of finding the right page to write directly instead of having to clean and then write, which would be slow. The trim command wasn't needed in mechanical hard disks so it didn't exist.
