Yes, it would only affect new user registrations. Worst case would be that two users get the same Wiki account.
e.g:
VB username 1: "test_test"
VB username 2: "test test"
Both would use the "Test test" wiki user account, because all '_' will be converted to ' '.

For tests I created an user "_test : ? ^ & ( ) *" in VB, even there the user was able to use the wiki with this username: "Test : ? ^ & ( ) *" and the userpage was: "User:Test_:_%3F_^_%26_(_)_*"
As you see the first char should not be an '_' or an ' ' else it just gets removed, the other chars did not really make a problem.

I need to do some more tests to see what chars we really need to disallow.
