The Content Translation beta feature long time back introduced the contributions menu entry point where users could access directly the few options to contribute that were exposed in the Contributions page for a new contribution (translation, upload media and new page). Some of these options (translations and upload media) were exposed through the user menu for the new version of Vector or a popover when hovering "Contributions" on previous versions.

Contribution popover (previous version of Vector)	User menu (new version of Vector)	Proposed

With the development of the Contribute entry point (T322740) options to contribute are expected to grow. In order to avoid crowding user menus (T330611), this ticket proposes to remove these contribution options from the menus.
In this way, the focus to contribute is on a single option for contributions. There, users will have the tools to navigate the different possibilities of contribution.

We can consider this change once the Contribute option is widely available: T327874: Enable the new Special:Contribute page entry point for all Wikipedias on desktop and mobile
