Squid CONNECT ACL Problem

Hello Squid Users and Developers,
Squid has ACL For CONNECT Method
it is

acl SSL_ports port 443 563
acl CONNECT method CONNECT
http_access deny CONNECT !SSL_ports

Why squid has default behaviour to deny CONNECT requests on non-standard SSL
Ports
Some sites are implementing SSL on non-standard SSL Port
So squid's this behaviour is creating problem in surfing such site.
I am planning to allow CONNECT on non-standard SSL Port as well but before
that i want to know the reasons for default DENY action.
Waiting for Reply
