Can we use both Classic & Responsive SSP after 25C?

Summary:

I just want to clarify that whether we will be able to use both Classic and Responsive Self Service Procurement after 25C. I have seen in the FAQ discussion that the classic version will remain there and there will be no fixes, but at the same FAQ there is an answer to the question that "Until we retire the classic application in 25C, it is possible to have both applications available."

My concern here is that we are creating PR from Maintenance Work Order page, when I enable the default option for RSSP and try to create the PR directly from the Maintenance Work Order page it is still routing me to the Classic SSP page.
