Exactly. They're static C structs; if you want them modifiable from
Tcl you'll need to rewrite them and everything touching them to deal
with some new, equivalent, class variables, instead.
Or you write tcl commands that invoke C functions that blat new
universal values into them instead - that doesn't give per-object
variability, though.
