No. I disagree with what you say.

Adobe respects Unicode. It does not have to agree with 
the UTF8 encoding of it.

PDF is an ISO standard now, so is properly published,
and anyone can conform with what has been published.

This is miles (!) better than many other attempts to impose 
acceptance of other preferences for encoding of data.
The PDF specs say what is acceptable in all the different
circumstances where character data is used for different
purposes, and it provides mechanisms for arbitrary content
to be translated to Unicode code-points, irrespective of 
how individual fonts may be encoded.

Specifying an internal representation of a symbolic link 
is a programmatic thing, not a textual content thing.
So of course you need to follow the published syntax.

Thus the question here reduces to whether XeTeX, or the 
hyperref package, should ensure that whatever restrictions 
imposed by the published PDF spec are met, or whether 
the author needs to do it him/herself.

My advice is simply that if you restrict yourself to ASCII 
letters, then you will not face any difficulties.
This is pure pragmatism; nothing less.
