Drop column on declarative schema not working as expected

Question

I was playing on Magento 2.3 with Declarative Schema, and everything works very well when I added a new column do db_schema.xml and did a setup:upgrade.

However, when removing a column node from XML and performing setup:upgrade, the column was not removed.

I also tried with --safe-mode=0, adding disabled="true", flushing cache before, etc, but the column is still there.

Am I missing something?

You have to regenerate whitelist for your module every time you delete something in your db_schema.xml
