I would have done that, but there are 2 usages of it:

rsc/inc/rscdef.hxx:213:typedef UniqueIndex<RscFile> RscSubFileTab;
tools/inc/tools/pstm.hxx:152:typedef UniqueIndex<SvPersistBase> 
SvPersistUIdx;

UniqueIndex is both a map and a key generator. It also tries to keep the 
key space as small as possible
The key generating part appears to be quite necessary to how the RSC 
module functions.

Suggestions?
