I actually wondered about that and had the frontend "allowBlank" check
initially such that the value was only required if the name field was set (as
the variable simply gets deleted otherwise), but I then changed it to both to
be required, as allowing something more is almost always easier to do in the
future compared to restricting it, especially if it involves API exposed schema.

Anyhow, the UI part would need now also adaption to make your change fully work
also there.

Applied, thanks!
