It isn't an XeTeX/XeLaTeX issue ... it is an inherent limitation of the PDF
file format.

The best XeTeX could do .. is type to:

1) provide ways of controlling the subsetting or not of fonts and allow
editing or customisation of ToUnicode mappings on one hand; and

2) add some tagging algorithms and add ActualText attributes

But this isn't going to get you very far without creating a whole
information ecosystem for the PDFs.

Alternatively, it could add support for an alternative format to PDFs that
doesn't suffer the same problems as PDF documents.
