SysMLv2: Webel: Redefining a parameter or port (or a directed feature of such) in a binding connector's context provides a "clean" binding target (as opposed to binding to an inherited feature). BUT it's not always necessary (confirmed by SysMLv2 samples)

SysML2.0: Webel: Suggest the spec needs to clarify through more examples whether binding to a parameter or port (or a directed feature of such) that has NOT been redefined in the binding connector context (is just inherited) is valid [it is]
That performing such redefinitions JUST to provide "clean" binding targets is NOT always necessary see this SysMLv2 PILOT GitHub sample showing flow connectors between inherited parameters:

[DISPLAY, MODELLING, PATTERN, STYLE, TIP, TOOL]{STRONG} Webel Best Practice: SysMLv2: VERY STRONG RECOMMENDATION: Prefer Webel "Trust the Type" i/o parameter naming and Webel display conventions over verbose parameter names. To find out how attend the Webel SysMLv2 course!
