I am obsessive about backwards compatibility, and I test back to Netscape 2.0 (the first JS platform). The magic of JS feature check abilities is that you can totally cover every browser.
There's a little bit of testing you have to do, because early browser wars resulted in intentionally added incompatibility gotchas, but it's not that bad.
The Web is an amazing and unique platform unlike almost any other available to us. We're so lucky to have it.
