[Zope] Is Structured Text Broken in Zope 2.4x ???

I’m a Zope newbie who is hoping to more-or-less adopt New Religion from the
Structured Text is a very attractive feature of Zope, but I’ve found some
major problems with the Structured Text implementation in Zope 2.4x, and I
suspect that many others must have encountered the same issues.
My current testing is with Zope 2.4.1 on Windows 2000.
I can easily create Structured Text documents (say "stxdoc.stx") in the
members areas of www.zope.org and cmf.zope.org that html-render as
documented and expected.
However those same documents render significantly differently on my local
installation of Zope 2.4.1 when called from a dtml document or dtml method:
<dtml-var stxdoc.stx fmt="structured-text">
Specifically, hierarchical bulleted and numbered lists (i.e. outlines)
render with ugly spacing and tables don't render at all. A possible patch
for the spacing problem appears in a comment by datagrok at the bottom of
this ZWiki page:
Additional info on the lack of table rendering appears in this post:
Additional Zope 2.4.x Structured Text issues are documented by Ivan Kurmanov
in this post:
and by Simon Brunning in this post:
However, an even much more severe problem lurks in Zope 2.4x. That is that
the structured-text() method in Products.PythonScripts.standard is badly,
badly broken. In addition to the problems listed above, this method doesn’t
html-render links. (i.e. "link name”:http://mydomain.com does *not* cook
into <a href=”http://mydomain.com”>link name</a> , but rather the input text
is copied without any cooking at all!)
The method also sometimes performs incorrect double html_quoting. For
example, structured text that is indented following a paragraph ending in a
double colon (“::”) , is properly cooked into a <pre></pre> tag in the html
output. Unfortunately however, the *content* of the tag is html_quoted
*twice* in the output.
This is quite bad news, because the structured_text method in PythonScripts
is specifically needed for the convenient use of structured text from Zope
Page Templates and restricted Python Scripts:
Rendering structured text from a Zope Page Template:
<span tal:define="global pss modules/Products.PythonScripts.standard">
Rendering structured text from a restricted Script (Python):
# Import the standard method "structured_text()"
from Products.PythonScripts.standard import structured_text
# return a cooked page from a structured text source file
print structured_text(getattr(context, "stxdoc.stx"))
These bugs appear to be a significant barrier to practical use of Zope Page
Am I missing something?
Is the problem simply that StructuredTextNG was used in Zope 2.4x before it
was fully debugged?
Should Zope just revert to ClassicStructuredText (which was at least
