Thanks for your report. I'm sorry, I was wrong at altering regexp
generation code. Can you try the attached patch? (Undo the last patch
and apply the attached patch to the fresh source, please.)

I expect the revised patch fills that bill.

Do you mean that `ConTeXt-paragraph-commands' doesn't include the
leading backslash? Then it isn't specific to interactive customization.
It is desgined after LaTeX counterpart, which also doesn't include the
leading backslash.

You can use
(add-hook 'LaTeX-mode-hook
  (lambda ()
     (add-hook 'find-file-hook
        (lambda ()
           (setq paragraph-start "abc")) <-- Set whatever you like
        nil t)))
in your init file if you really need, but I'd like you to try the patch
below first.
