Well, the idea was to instead use ISO TR24731-1 and TR24731-2 (see Appendix in help file): functions optionally part of standard C. The problem is that few vendors have bothered to implement these functions. With new people on the C Standards Committee, there seem to be interest in removing TR24731-1 and TR24731-2.
I don't really know what is best right now. Since <strsafe.h> is mostly a bunch of inline functions, you always have the option of making it a private copy and remove the deprecate annotations.
