Is this really an issue today?  Shouldn't Texinfo rather move on and
make the EC fonts mandatory?

Well, for cut and paste, `\circ` is *not* an alternative, since it
maps to U+25E6 (WHITE BULLET) in font `cmsy10.pfb`.  This might not be
an issue in math, but for code listings typeset with typewriter it
would be really nice to get it right.
