How do South Americans feel about including the Concacaf teams?

As a Canadian American I loved it, just happy we got to play games at this level. Felt bigger than World Cup qualifiers (because Canada for 24 years couldn’t even make the Hex in Concacaf).

It feels like a true Copa America - but do our South American friends like having Concacaf or would rather keep it to 12 teams just inviting say USA and Mexico?
