before “technomic” stems, the goofies were just not possible, unless a guy fitted Schwinn “rams horn” handlebars.
bigger bikes often had longer top tubes, as gravity strikes back, not as comfortable. 25-35mm of shrinkage in the spine is pretty common.
What big bikes do have are longer front centers. That can help comfort and stability. Plenty of other elements can counteract that, but a reasonable generalization.
