I have only very limited experience with userinfo. However, the one I 
have doesn't suggest it gets disallowed. There is not much difference 
between sending passwords in clear in email as:

go to page http://foo.org/bar
user: us_only
password: secret


go to page http://us_only:secret@foo.org/bar

when people are aware of the fact that this page isn't for everybody's 
eyes. However, the later is way more practical.

Regards,    Martin.
