No,
- this needs to be loaded with LD_PRELOAD because it overrides very common 
symbols of the libc (fopen, etc..) and thus it needs to be loaded in a special 
way so that the symbols of vsipreload.so are actually used and not the libc 
ones.
- it is better to keep it in a separate library, because I can easily imagine 
that having fopen() and the like re-defined in libgdal.so could cause serious 
mess.

So all in all, this is a convenient trick, but this remains an experimental & 
somewhat dangerous hack to be used in last resort.
