The "executable bit" is only an hits (for program in path). Every program,
which is readable is also executable! Classical examples: execute the program as argument of the dynamic linker, executing scripts using the interpreter. Eventually a copy of the program and then changing permission bits. In short time the exploiters could use such work-arounds. So execution bit should not be used for security reasons

You don't get it. The interpreter is a specialized interpreter
for .desktop files, which does all the parse-and-launch stuff. *It* checks the state of the executable bit on the .desktop files that it is invoked with, and *nothing else runs programs named in .desktop files at all*.
