No, because it already lists ~/.fonts which gives a user an easy 
opportunity to make his/her favourite fonts available without digging 
into fontconfig (if only this option were documented...).

That might be a good idea.
Be sure to include a dependency to the font package you choose for default,
e.g. font-bh-ttf for Luxi Sans,
or font-bitstream-vera-ttf for Bitstream Vera Sans;
font-cantarell-otf for Cantarell is also a good choice.
(I'd suggest not to choose a default from a texlive font package because 
they are too big for a dependency.)
