I am thinking how to make it more general but this would fix tbl_strata if something like this is added to tbl_strata:

  # running any additional mods
  get_theme_element("tbl_hierarchical-fn:addnl-fn-to-run", default = identity) |>
    do.call(list(x))

I'm not sure Daniel would be open to modifying tbl_strata() for this. Is it possible to do all within crane?

Let's no introduce chagnes into gtsummary for this. I see two potential solutions.

1. Abandon, and whenever we use this function in the catalog, we specify the .header argument to remove teh bold.
2. We could also set pkgwide-fun:pre_conversion with a function that removes the markdown bold syntax from from spanning headers in x$table_styling. This would occur jsut before the gtsummary table is converted to flextable.
