chore(router): update generic names

[MichaelDeBoey]

Follow-up of @brophdawg11's #10843 for the reasons mentioned in my remark (see #10843 (review))

In the light of named tuple elements, I've seen something passing by to do the same for generic elements as well, so I think it would be better to have long names instead
