There is a publisher selected expiration date as part of the signed exchange which the client inspects. The expiration also cannot be set to more than 7 days in the future on creation. This minimizes, but of course does not eliminate, this risk.

It also makes signed exchanges completely unusable for delivering packages offline. (E.g. the USB stick scenario)
What a bummer.
Browsers could have a setting to optionally display the content anyway, along with a warning to the effect of "site X is trying to show an archive of site Y", similar to how we currently handle expired or self-signed SSL certificates.
