As for the actual change, it is limited to the

will be added:

[connectivity]

See the manual page for NetworkManager.conf(5) for the details of
what
these settings do.

Please let me know if you have questions or think there are good
reasons not to enable this feature. If there is no response by the
end
of the week, I'd like to proceed with a enabling this in Quantal and
making sure it gets well tested.
I think that a significant fraction of Ubuntu's user base is
(reasonably)
very sensitive about privacy issues.  While this is no worse the the
NTP
check that already exists (that is controversial), I don't think it
should be enabled by default.
I think that for those who are concerned, this is trivial to disable.
But, I think what happens for those who are, is that Ubuntu "does the
right thing" by default.  If you're at a hotel or other location that
captures for a login page, you won't get your mail and apt and ... all
downloading bogus stuff.
First, I do a fair amount of travelling for $WORK, so I know all about
these. For people who travel, they already know about logging into the
web page when you get to the hotel.

This kind of check doesn't actually guarantee anything since different
places handle these things differently.  Even if the proposed check
works, if a hotel captures and redirects port 25 or 587 (yes, port 587
redirection happens, although it's positively brain dead and rare) then
your mail is still screwed.

If you're connected of not is on a port by port basis, so I don't think
this reliably solves the problem in any case.
Solving it for a good proportion of cases is better than not solving it
at all.

It drives me nuts that Evolution and gnome-xchat spew error messages
before I log into a portal, when this problem is already solved on other
operating systems by using essentially the same technique.
I've got absolutely no objection to this if it's defaulted off for people like
you that want it.
I clearly don't agree it should be defaulted to off. That's one of the best feature I discovered in Android ICS (4.0): "seems like your connexion is behind a captive portal", just click on it, and be able to log in! I really enjoyed the first experience and was really surprised to see it.

I think this kind of small delightedness is what makes a shining user experience, and that's why it should be on by default for the user. Then, if people really concerns about "privacy" (which is the not that different than the automatic apt-get update done in the cron job, or by the proxy detection in vino…), then they can help implementing some UI for deactivating that in a privacy panel for their favorite desktop environment.
