And Debian has to put in a fair bit of work to ensure that spam
doesn't make its way into the system. Registration is one of the ways
that Launchpad uses to reduce the impact of spam (it certainly doesn't
stop all cases, but it does make a difference and helps in clean up).
Launchpad certainly isn't alone in this regard.
Furthermore, lack of registration and authenticated access means that

Most OpenID relying party sites uses session cookies to identify the
user after authentication. It certainly is possible to design an RP
that doesn't rely on cookies for client side state, but it will either
be via a cookie substitute (e.g. session identifier in the URL) or by
asking the user to reauthenticate every time they perform a restricted
So OpenID is not going to save you from session cookies. It will help
with managing passwords though.

OpenID is not going to make a difference to whether you need a
Launchpad account in order to use Launchpad. When Launchpad is an
OpenID RP, it'll likely mean two things:
1. you can log into your account using OpenID authentication as the
2. logging in with an unknown OpenID identifier might create an
account associated with that identifier.
If you want Launchpad to send you email, you'd still need to go
through the email validation process. While an OpenID provider can
provide an email address to the RP, this is self asserted and not much
different from a user entering an email address into a registration
form. Any responsible site is going to verify that the owner of that
address really wants to receive mail before accepting it.
