I completely agree. I do like that imports do not automatically create a new static list but losing the ability to add imported contacts during the import process to an existing list is a real issue. Not only is it more steps, but if you have workflows running that exclude contacts based on certain lists, the newly imported contacts could be enrolled in a workflow before the additional steps to add them to a list are completed. This literally could result in contacts being inadvertently emailed inbetween getting them imported, creating a new list and then adding them to an existing list.
