Numberers are ignored by the LaTeX renderer

When the following file is rendered with raco scribble --pdf file.scrbl, the sections SecA, SecB and SecC are still numbered using Arabic numbers in the PDF.

I think it would be better if the LaTeX/PDF output was consistent with the HTML one. The sections could be typeset as \section*, and have their number hardcoded in the title, or, possibly better, by redefining \thesection to the constant, pre-computed “number” and restoring it immediately after:

\let\oldthesection\thesection
\renewcommand{\thesection}{A}
\section{SecA}
\let\thesection\oldthesection

…

\let\oldthesection\thesection
\renewcommand{\thesection}{B}
\section{SecB}
\let\thesection\oldthesection

#lang scribble/manual
@require[scribble/core]
@(define my-numberer
   (make-numberer (λ (current parents)
                    (values (list-ref '("A" "B" "C" "D" "…")
                                      (sub1 current))
                            (add1 current))) 1))
@title{Foo}
@(table-of-contents)
@section[#:style (style #f (list my-numberer))]{SecA}
@subsection{SubAA}
@subsubsection{SubAAA}
@subsubsection{SubAAB}
@subsection{SubAB}
@subsubsection{SubABA}
@subsubsection{SubABB}
@section[#:style (style #f (list my-numberer))]{SecB}
@section[#:style (style #f (list my-numberer))]{SecC}

Reproduce the issue with raco scribble --pdf file.scrbl using the Scribble source shown in the report, then trace the LaTeX/PDF renderer's handling of section numberers. Done means custom numberers produce section labels in PDF consistently with HTML, including the A/B/C example.
