I dunno; I think Tradcoding would go beyond regular modern coding, and rather imply some kind of regressive Nara Smith "first grind and sift the flour in your kitchen"-style programming.
No Internet connection, no cache of ecosystem packages, no digitized searchable reference docs; you sit in a room with a computer and a bookshelf of printed SDK manuals, and you make it work. I.e. the 1970s IBM mainframe coding experience!
If you have a good stdlib (which in my case would mean something like Java for its extensive data structures) Tradcoding is entirely possible.
This isn't terribly far from "Knuth-coding" to call it something - imagining the program in WEB in its purest form and documenting what it does, almost irregardless of the actual programing language and how it is done.
