SYSML2_ — Change graphical notation for use cases to elliptic elements

In the SysML v2 the graphical notation for use cases is a box with rounded corners containing the stereotype "use case" and the use case name.
From the very beginning of UML and SysML v1.x use cases are visualized as elliptic elements. Nearly all people that have ever used or seen UML or SysML in the past are familiar with that notation. So why change it for SysML v2 here? It is not necessary from my perspective.
A box with many textual things inside is not a good idea for a graphical language. Graphical languages should use as less text as possible. Instead they should use different graphical shapes, different stroke widths, stroke types and icons to express the semantics and what is modeled.
A user should be able to recognize a diagram element on a first side, looking at a diagram drawing form far away. It should not be necessary to read all details to recognize that is a use case diagram and not any other diagram by reading the stereotype text elements first!
