The issue is that we cannot use trademarked names inappropriately. An
obvious requirement of trademark law is that we cannot present the name
'Times New Roman' when refering to Timmons. Similarly, we cannot
represent the name 'Times New Roman Bold' if we have only 'Times New
Roman' and are synthesizing the bold variant with software.

Because of these trademark issues, fontconfig simply doesn't permit the
*listing* of such aliases. It certainly does allow the substitution when
such names are directly requested, so applications which ask for 'Times
New Roman Bold' can get a synthetic bold face.

You can use this substitution mechanism to replace one family for
another when certain styles are requested. The only thing you cannot do
is provide that information through the font listing API; that API is
limited to presenting only information extracted directly from the font
files themselves.
