Which is a moot case since there are at least 5 other browsers for XP who
support SNI.

"SSL support with SNI on shared IP addresses requires that the user's
browser supports SNI. Most modern web browsers support it (e.g., IE 7 and
above, Firefox, Opera, and Chrome). However, there are a few outlier
exceptions:

    Any Internet Explorer browser on Windows XP
    Chrome 5 and older on Windows XP
    Blackberry web browser
    Windows Mobile phones up to version 6.5
    Android mobile phone default browser on Android OS 2.x"
