I thought this was a major issue, until I realized there is a workaround.
The trick is to use the "end date" instead of the "duration" field. You can adjust end date visually by simply dragging the end of the task in the Gantt view. Moreover, if you have to edit the start date of the task it's better to do it visually by dragging it, as that will preserve the actual duration of the task.
TBH I'm not really sure if "duration" field is used for any calculation or report, but it definitely doesn't affect how the Gantt is rendered.

I confirm. The gantt chart uses the duration of the tasks (default to 1 day) to determine the duration of the projects.
