I wouldn't be opposed to making the definition of expressway=yes to describe divided highways with limited cross traffic... Along with some bonus rendering on them regardless of importance to distinguish them.

Take this PennDOT highway map for example: [https://gis.penndot.gov/BPR\_PDF\_FILES/MAPS/Statewide/otm/2020\_OTM\_FB.pdf][https_gis.penndot.gov_BPR_PDF_FILES_MAPS_Statewide_otm_2020_OTM_FB.pdf]

This way a major through route keeps the same line color for it's duration but expressway sections are shown with a double line instead of single. The American map style can do something similar so sections of highway tagged as expressway=yes or access\_control=full\|partial get an expressway line style regardless of highway=\* classification (excluding some on the lower end).
