This change is also removing the ability to control the categories alignment, ideally, we should keep the maximum possible customizations to our users.

I would suggest adding an extra element/class when the message is displayed and control it with CSS.

[LavaGolem]

@gabrielcaires that is also a solution, my concern is that adding the align property can cause more trouble that the benefit.

Also, I don't see in the block settings anywhere that you can change the alignment even if it is enabled :

Is there some other place where it can be changed?

[gabrielcaires]

@LavaGolem The feature is displayed, above the block when you select.

[LavaGolem]

@gabrielcaires so instead of removing align option from a block, I'm setting a align center by default. This will enable to users to change the alignment but we don't care if the decision to do it is on an Invalid usage block.
this also works on different themes :D
