[ZPT] index_html a script, not a template

[1st: Sorry for crossposting, but now it actually makes sense]

"Maybe scripts, rather than templates will commonly be URL target."

Until the last couple of days I'have always made DTML Methods or DTML
Documents for everything that users type into the addressbar like
"index_html" or "about".
I.e. I start with a template and most likely end up in a template.
It shouldn't be like that, should it, always. Because some of my templates
might look like this:
<dtml-var standard_html_header>
<dtml-if "iscooluser_externalpy_orscript()">
   <dtml-with foo><dtml-var showthat></dtml-with>
<dtml-else>
   <dtml-with bar><dtml-var showthis></dtml-with>
</dtml-if>
<dtml-var standard_html_footer>

Recently my sites are filled with sometimes three times as many python
scripts as DTML objects. And Jerome Alets Zshell really opened my eyes for
loosing templates.

Am I alone on using templating objects for URL-hitting objects? What are the
implications (performance, scalability in terms of feature changes, etc.) of
using Python Scripts or External Method instead of templates?
Is there a paradigm shift with these promising Page Templates (see quote
above)?
Advice from people with zen?!?!


Trying to see as long as possible, Peter
