Screenreaders are by definition a tiny market share at most sites.
If that is a reason not to care about them, then let's forget all
about accessibility.

I know that's not what you meant, but it's the same underlying argument.

Browser-specific authoring is the Root Of All Evil on the Web.

Seriously, that's a lot like authoring for "both browsers".  By doing
that you are contributing to
  * lock-out (of people with different equipment)
  * lock-in (of people with supported equipment, all of which is
Never limit your support to users of expensive equipment - you are
penalising them the cost of it.
Never limit your support to users of proprietary equipment - you are
leaving them hostage to vendors.
Above all, don't make hostages to Windows.  Even if you discount the
fact that it's grossly overpriced and requires new and expensive hardware
every few years, you're forcing users to expose themselves to the
World of Viruses.

If there are legitimate reasons to present things differently, you should
do so by empowering your users to choose, not by second-guessing their
needs.  The kind of user-options offered by mod_accessibility do this,
and if you think its output can be tailored for optimal presentation
with particular screenreaders, I'm listening.
