This command matches Org Mode API style.

I hope Org Mode can have this built-in. Because there are some other dynamic blocks. They can use this dispatcher function.

For example org-gantt dynamic block, I write a function manually:

#+begin_src emacs-lisp
(defun org-insert-dblock:org-gantt ()
  "Insert org-gantt dynamic block."
  (interactive)
  (org-create-dblock
   (list :name "org-gantt"
         :file "data/images/project-gantt-chart.png"
         :imagemagick t
         :tikz-options "scale=1.5, every node/.style={scale=1.5}"
         :weekend-style "{draw=blue!10, line width=1pt}"
         :workday-style "{draw=blue!5, line width=.75pt}"
         :show-progress 'if-value
         :progress-source 'cookie-clocksum
         :no-date-headlines 'inactive
         :parameters "y unit title=.7cm, y unit chart=.9cm"
         :tags-group-style '(("test"."group label font=\\color{blue}")
                             ("toast"."group label font=\\color{green}"))
         :tags-bar-style '(("test"."bar label font=\\color{blue}")
                           ("toast"."bar label font=\\color{green}")))))
#+end_src

Org defines C-c C-x i as org-insert-columns-dblock. Instead, it could call the org-insert-dblock dispatcher shown here. The original org-insert-columns-dblock would be one among other dblock inserters.

Possible dblocks:
  org-insert-columns-dblock
  org-clock-report
  propview
  invoice
  org-insert-dblock:aggregate
  org-insert-dblock:join
  org-insert-dblock:transpose

Any future dblock inserter would be taken into account by the dispatcher just by providing an autoloadable org-insert-dblock:something function.
