I'd like to build in functionality so this "just works" across any of my projects, I can't think of scenarios where I'd not want to return the user to the page they tried to access.

I'm thinking accounts-entry might be the right level to implement this feature.

Agree this belongs in accounts-entry?

We could make this a config variable if some of you might not want the behavior.
