Are there any pre-Unicode 5.2 applications still in existence?

Hi Folks,

I have learned that:

    In some versions prior to Unicode 5.2, conformance clause C7
    allowed the deletion of noncharacter code points [1]

Are there still in existence applications which delete noncharacter code points from strings?

Are there any pre-Unicode 5.2 applications still in existence?

The paper at [1] describes the security risk with deleting noncharacter code points. Is this risk still a concern, or can one assume that there are no more applications which delete noncharacter code points?
