You described the samba wizard in post #27.
That is the part about typing the path then entering the user and password in sources.
What is confusing is they still include the "browse" option that does not work anymore. I guess they could modify that to "type the network address here, they follow the directions".
I had to read this thread and your post #27 to understand it, but it is easy.
Yes plus Windows shares need credentials added if needed. In my case, I added a second windows user with credentials since my main user did not have a login and password assigned and then I added that user to the windows "share with" settings. Then every path in Kodi needed to be re-written to include the credentials. It seems there are many ways of doing this task and I think a built-in wizard would really help.
