Text can appear to the right of a checkbox.

It is traditional. Checkboxes have text to the right of them. To the point
it seems incomplete, like something is missing, if the label isn't there.
It is even hard to click...

I fear there may be some ideology to the lack of this text in Deform.
It certainly would already be there if you thought it important... Of
course I understand that Deform already offers a label that appears on the
top and some help text that may appear below each control. I just think
it would be nice to offer this additional text possibility for checkboxes,
out of the box.

In the implementation, I have chosen a "text" attribute on the schema itself.
The name of the attribute is very negotiable, I just don't have any
better ideas. When the attribute is lacking, the label doesn't appear.

Really hoping you don't have serious objections to this...
