It is, at least now.
On zope-dev, it was discussed how this
restriction can be removed in the future in a controlled way
(you do not want to make everything overwritable).
To avoid the problem, you can add in your class method something
like:
<dtml-if index_html_specialized>
<dmtl-var index_html_specialized>
<dtml-else>
....
</dtml-if>
and define "index_html_specialized" in your instance, whenever
you would like to have specialized behaviour.
