Salesforce CPQ Package Expiration

I have installed Salesforce CPQ package in my DEV org and it shows the expiration date as "Does not Expire ". Does this mean Salesforce CPQ package is been supported for life time in Developer Edition orgs? I did not find any link/article regarding the same.

Such a question is best posted on Salesforce’s own forums as there may be very few people in these forums that work with the CPQ product.
