benignuman-
I was unaware of the Rikanti’s usage of Targum Yonosan (a citation would be appreciated).
Here is one example. Top of second column:

Haleivi-
The Rikanti is after the Ramban, so you aren’t really adding much by saying that someone after the Ramban quotes it too.
I was only responding to what you yourself wrote:
“The Ramban rarely mentions it. So, if other Rishonim refer to it one time less than the Ramban, they won’t mention it at all.“
And the Rikanati and Tosafos both cite it as Targum Yonasan.
