I’ve used symlinked bashrc and other files and edited them with Vim through their symlinks and never had the sorts of problem you theorized about. I would consider the behavior you outline to be an editor bug. Symlinks are pretty important and any editor that would destroy a symlink and replace it with a regular file is clearly misbehaving software IMO.
