I need to preset the values of attributes activationUntil and activationFrom to today and today+356 days respectively. I don't want to use an init rule on the attributes themselves, since it may vary for each type. I want the values to be preset only for the creation feature of a given type.

You can see that initRules also work in features in the options tag.
Using the following code in the create feature of your type will prefill the values of attributes activationFrom and activationUntil.
<options>
<completionRedirectURL>feature://identity-internal-hub.identity-internal-read/{routeObjectId}</completionRedirectURL>
