Where is a definitive source about "which key should be mapped to what". 
Somehow, I don't really like the idea of having a non-default mapping, 
because it will most certainly cause bugs in some other corner of the system 
in the worst moment possible.

Mostly Debian sarge, xlibs 4.3.0.dfsg.1-8, rebooted every day (i.e. also 
between update and appearance of the problem.)

This is not about opinions, but about "who sets the standard". Obviously, the 
whole issue was started when the X-developers decided to change their 
opinion. Now nobody knows who actually caused the bug...

If I see it correctly now, altwin:left_meta_win is not set by default. 
Therefore we should expect the dummy user not to have it set either, and 
TeXmacs should work out of the box. Does that mean that my patch should be 
used after all? (As I understand it now, all it does is to check for the case 
that altwin:left_meta_win is not set and work around it.)

xkb_keymap {
        xkb_keycodes  { include "xfree86+aliases(qwertz)"       };
        xkb_types     { include "complete"      };
        xkb_compat    { include "complete"      };
        xkb_symbols   { include "pc/pc(pc105)+pc/de(nodeadkeys)"        };
        xkb_geometry  { include "pc(pc105)"     };
};
