Forced dependency of repeating date with unlimited values no good UX

From the users point of view the unlimited value option of a field means that the user can add/input multiple separate items of a field bundle. In this case the user ist awaiting multiple dates. While checking repeating date option makes it possible to let ONE of these multiple items repeat daily, weekly, or something similar. In UI logic of dates and calendars, this has nothing to do with a hidden multiple added field item logic.

From the users point of view it is not understandable, why setting up the date field with the option checked to have a repeating date available, forces him to use the field with "unlimited value" (selector not changeable no more) option activated and without the option to use this for additional field entries. And how does that interfere with the option to have multiple repeating dates. As of the user understands it. I don't ask how to achieve this. I try to explain where the UI is logically not good designed.

Even if this is maybe forced by the way how this field should work I am rather not sure if this is a feature request or a bug. From the UX point of view this input logic is wrong. An option to set up a "value which repeats" is not a field with unlimited values, it is ONE value which has an addtitional parameter which can be set to make it repeat frequently.

The picture below also demonstrates very well how illogically this causes a form field failure in drupal node add forms, since these node forms have the same logic like the user, which gets confused by this behavior.
