Automatic length of video when using Image Node in compositore Post Title

When adding a new Image Node on compositor and selecting a video as an input, wouldn't it be more intuitive if the node automatically checked for it’s length (Frames property) setting it to the right value? I know I can hit the button in the sidebar to make this happen but when importing a video in the node it’s to be expected that the user might want to work with the whole video having all the frames there in most cases.
