• caption
• fancyvrb
• graphicx

• caption

   acmart.dtx:3369:\RequirePackage{caption, float}

  acmart.dtx:3249:      \RequirePackage[tt=false]{libertine}
  acmart.dtx:3252:       \RequirePackage[tt=false, type1=true]{libertine}

Should the page at ACM be updated or are these inteded to be included? (cc @Craig-Rodkin)
