Thank you.

Altering the parse tree seems a bit drastic to me, though. See below.

We don't need to add "caption" to the default packages set. We can
specify that this feature is available only if that package is required.

We could replace

  (caption (org-latex--caption/label-string ...))

with

  (label (let ((label (org-element-property :name table)))
           (and label (format "\\label{%s}\n" (org-export-solidify-link-text 
label)))))

and change "caption" into "label" later in the function.

WDYT?
