If we change the border to be 1 for printindex tables, it should be
because the output is better also in web browsers.  I am not sure that
it is the case.

Regarding the change of "0" to "", it looks wrong to me, no border
attribute has been specified with a "0" for a long time and correctly
rendered.  The border attribute is not in HTML5 anymore, but it is not a
reason to remove 0 as a possible value -- nor is it a reason to stop
generating it.

That being said, currently the border of tables output when formatting
@multitable, @printindex or @cartouche cannot be customized in HTML
texi2any output except by overriding the conversion functions.  I think
that it would be better to define classes and use CSS for the tables
borders.
