Liquibase Hub Registration No Longer Available?

According to https://github.com/liquibase/liquibase/pull/3886, new Liquibase Hub registrations are no longer enabled. I’m just starting a new POC with Liquibase and found that I’m unable to sign up for Liquibase Hub; assuming this was done on purpose? What does this mean for new users interested in integrating with Liquibase Hub?

Hi @pallazudatademo Thanks for joining the community.
What features or information were you looking to provide or do with your POC around Liquibase Hub?
It would be good feedback to pass back along.

Until then, based on feedback from our community, and after monitoring usage and interest, we’ve decided that it’s the right time to sunset Liquibase Hub, and shift our focus towards other, more highly-requested upgrades.

While we understand that this news may be disappointing to some, we’re confident that the changes coming to Liquibase will provide an even higher level of functionality. More information and exciting new features to come in the next few months.
