Why aren't area labels (text tags) dynamic?

Dimension text updates when the geometry is adjusted in length.

Area text tags are added to faces ( and the area value is set automatically according to the face size) - however - when the face size changes , the tag does not update.

Wouldn’t it make perfect sense for the area label to update and show the area of the face?

Of course, if you were to edit that label manually, then you would expect it to remain on the value that you changed it to. Just like dimensions.
