what impact the IDNA 2008 policy will have

It's actually IDNA 2010 since the RFC were all issued this year. 

ondomain name registrant's who have a domain that does not fall
underthe policy's permissible code-points, particularly symbol-based
domainnames.

Do note they are probably uncommon, at least at the second-level since
most (probably all) of the TLD never allowed them.

what in practice, will itmean if someone types in e.g. ?.com in
their browser under IDNA 2008?

Browser policy. But typically, users will be presented with an error
message.

Will IDNA 2008 not allow the domain registrant to satisfy a user's
queryby forwarding them on to a different domain name?

Yes, browsers can (not MUST, CAN) perform mapping from what the user
typed to a legal domain name.
