--- Comment #1 from Liam Powell <liam at liampwll dot com> ---
The solution for this is to presumably to just not allow descendant types to
have alignment which is incompatible with the parent type as the Alignment
aspect can already be specified as any value on the parent type. Setting
`Alignment => Standard'Maximum_Alignment` everywhere that uses Size'Class also
works.
