How is substituting fonts in a wine registry entry a predefined API behaviour?

This is a minimal regedit file that fixes my application:

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
NT\CurrentVersion\FontSubstitutes]
"System"="MS Shell Dlg"

[HKEY_USERS\S-1-5-4\Software\Wine\Fonts\Replacements]
"MS UI Gothic"="Sazanami Gothic"

Note that while the System font has to be redefined in a standard Windows
location MS UI Gothic does not. Which in my book means that Wine can do
whatever it wants as long as the MS UI Gothic ends up having the needed glyphs.

Wine is supposed to be 1.0. If there are features that do not work out of the
box and are only documented by the source these might be considered something
experimental but not something the users are supposed to know and use.

There's no point as long as the feature is broken anyway.

I see two problems here:

1) the default font does not have glyphs for the current locale.
 - my application does not explicitly choose a font. This means there must be
some 'default font' which is expected to work for the current locale on Windows
but does not on Wine

2) font linking relies on certain fonts to be substituted (or copied from
Windows) manually but does not produce any warning if they are not
 - for this to work out of the box font linking should 
  a) find some Japanese fonts and substitute them for fonts that are expected
to have Japanese glyphs on Windows - MS (P|UI |)Gothic, MS (P|)Mincho. MS Core
fonts (Arial, Times New Roman, Courier) are available so one could expect these
to be installed if needed.
  b) substitute the default font and system fonts that are expected to 'Just
work' with one of those. This is currently done for MS Shell Dlg but at least
System should be substituted as well. 
Some people also substitute Terminal, Fixedsys, MS Serif, and MS Sans Serif. I
am not sure which of these are really used but at lest the default font (which
appears to be System) should work.
