Does it ever make sense to delete attributes?

If not, should we remove the deleters, and make all attributes behave as 'required'?

-> If so, should we change the meaning of _props_req and _props?

What does the word "delete" mean in this case? If it is more akin to 'unset' or setting to undefined/null equivalent then that is certainly valid. If it means this object does not have a particular attribute anymore then it doesn't.

The second one. Trying to access a deleted attribute will result in an AttributeError

[brianjmiller]

Then 👍 to getting rid of deleters, don't think there is ever a case where an attribute should be removed. Presumably they would set to None if they need to "clear" a value which would be common. I don't think need to change _props and _props_req as the 'req' there is more akin to 'required' by the LRS for valid object (at least I think, feel free to correct if wrong).
