Whether such browser functionality can be used to satisfy this AA
success criterion depends upon which browsers are used by the target
audience. If only IE7 supports zoom and your users are not using IE7,
you need to use other techniques such as scalable fonts.

No,  using scalable fonts is still a sufficient technique to satisfy
this success criterion.

It is an accessibility issue, which is why it is included in WCAG.
However, there is some content for which it will not be possible to
scale the content in a way that doesn't require horizontal scaling
(e.g. large complex data tables).
