Improvements for Dimension tag?

> The Dimension tag doesn't impact compound layout. This means that while you can alter the size of an array in the middle of a compound, the offset of the members after that array won't be impacted. I'd rather like to see the layout adapt dynamically,

I'd be interested to know if this is still an improvement that could happen and if so is there anything I could do to help.

Start by locating the Dimension tag handling and compound layout logic, then inspect any existing tests covering arrays and member offsets. Done means agreeing on and implementing dynamic layout updates so members after a resized array receive adjusted offsets, with tests demonstrating that behavior.
