Not sure whether they should mimic GUI tools, however having tools which provide a graphical user interface, but are fully functional (or at least as much as is possible) from the CLI is the ideal way for a program to be in my opinion.
Where applicable, a command line option can be a great supplement when something that can be achieved via the GUI . For example, encoding a video to a certain codec, having a visual wrapper on this is a nice to have if converting one video or a few videos. However if that same application allows the ability to encode thousands of videos using the CLI option, its an added ability that is appreciated.
