Why on earth does the HTML sanitiser allow blacklisting?! That can't ever be safe to use, the set of HTML elements can always change.

Note that the API is split into XSS-safe and XSS-unsafe calls. The XSS-safe calls [0] have this noted for each of them (emphasis mine):

> Then drop any elements and attributes that are not allowed by the sanitizer configuration, and any that are considered XSS-unsafe (even if allowed by the configuration)

The XSS-unsafe functions are all named "unsafe". Although considering web programmers, maybe they should have been named "UnsafeDoNotUseOrYouWillBeFired".
