This was discussed about a year ago on the secnews server. According to
http://www.mozilla.org/projects/security/known-vulnerabilities.html , a
vulnerability was fixed in Firefox 1.0PR, Mozilla 1.7.3, and Thunderbird
0.8 regarding the "send page" menu option. My guess at the time was
that the "fix" was to convert "Send Page" menu option into the "Send
Link" option.
The issue revolves around remote code execution. The URL listed above
says: "The 'send page' function can overrun the heap on very long links.
With compelling content that people will want to forward to all their
friends and the right link this could be used to execute arbitrary code.'
So, it comes down to a security issue. As such, I'd be surprised if
someone wrote an extension to get around a security issue.... but then
again, maybe someone would.
That wouldn't cause them to convert 'Send Page' to 'Send Link'; in fact,
from your quote, it should apply completely to Send Link. That would
just cause them to fix it so it doesn't freak out on long URLs. :-P

I don't use it very often and when I do the "this page option" often
fails for some reason that I haven't looked into. Otherwise, I can
overlook the shortcomings you mentioned because, as I said, I don't use
it all that much. Good luck with your quest.
