Hello,
after working on this I realized that the org-tbl-calc-modes variables
is used only locally despite being declare globally. Maybe a remnant
from pre-lexical-binding times. Attached is a patch (on top of the
others one in this thread) that simplifies things a little.
Cheers,
Dan

Subject: [PATCH 4/4] org-table: Remove unused org-tbl-calc-modes variable
* org-table.el (org-tbl-calc-modes): Remove the variable declaration
as the varialble is only used as a local variable in `org-table-eval-formula'.
* org-table.el (org-table--set-calc-mode): Drop convenience macro.
* org-table.el (org-table-eval-formula): Rename `org-tbl-calc-modes`
local variable without the org-table prefix and usr the gained screen
real estate to avoid indirection through covenience macro.
