Yes. Although the whole BMP PUA seems to be used in one way or another I'm
wondering if there are blocks in this area which are *relatively* safe to
use; and whether there are areas or codepoints which are particularly
problematic.
How MS operating systems and applications treat PUA codepoints is of course
a particular concern simply because they are so widely used. - if mapping
glyphs to particular PUA codepoints causes problems under MS Windows or
Office then a majority of users of a font are likely to have those problems.
Conflicts with other widely used applications like Acrobat would also make
things very difficult.

That's why, in my earlier message, I wrote "as it comes to light" :-).
I also wonder whether or not things like what code page or locale the user
has selected affects things.
