Well, if SHA1 is required to implement the protocol, then a PHP version 
requirement of >= 4.3.0 becomes required to support it (according to 
PHP.net docs). This is not a problem for a Drupal 4.6+ implementation.

No reason in particular.  I'm trying to determine the feasibility of 
ever having this in core.  If the requirements for implementing it are 
so far out of the way, then I wouldn't even push for it ever going into 
core.  Additionally, if I thought it were ever going into core, then I 
would seek more consensus on its implementation than I would for a 
contrib module.
