Why do "Dynamic" and "Static" Symbol select differently?

"Dynamic" symbols cannot be selected by drag-selecting them with the "Direct Selection" tool as "Static" Symbols can be. I noticed this when moving an masked eyeball. This means I have to now remember to use the "Group" or "Normal" selection tool or select masked symbols by the Layers Panel.

Why would Dynamic Symbols have such a limitation?

Dynamic Symbols just don't seem very "dynamic" to me. The negatives keep out-weighing the positives, INMO.
