Can't resize GA5 when used as a VST2. Why?

If I want to use it in a host which isn’t VST3 compatible, why isn’t the GUI resizable??

VST 2 doesn’t support windows resizing, its a VST 3 feature…

“VST3 introduces a new approach to plug-in GUIs though window resizing, allowing for extremely flexible use of valuable screen space.”

Thanks for clarifying
