Since Vim completely depends on an external tag program for definition
navigation, so does Cream. But this is just semantics, it would be
simple add auto-tag generation onto the Alt-Down navigation for the
behavior you describe. Something like this is what other text editors
do, it feels integrated.

The difficulty is that this behavior can overwrite a manually written
tag file. Since tag files might contain manually-added references to
files outside of the current directory (e.g., Cream!), how would the
routine know how to re-generate an existing tag file with the same
logic? Is this per chance built into the tag file that we could parse?

Since it is easy to map the Ctag Generate add-on to a keystroke, I'm
hesitant to try and write logic to do it automatically, unless someone
can illustrate a way of distinguishing and maintaining the logic of
any non-Cream generated tag file that might be overwritten.
