If \pdfobjcompresslevel is set, then AR 5 isn't able to view
the file, e.g.:


AR5/Linux complains:

| There was an error opening this
| document. The file is damaged and
| could not be repaired.

and doesn't show the file.

In theory it is possible to limit object streams to additional
features such as bookmarks, links, anchors. With a traditional
cross ref table the file could still be viewed by AR5,
see PDF specification. But pdfTeX doesn't support this.
And I don't see the point in not having bookmarks, links, ...
Then ghostscript could be used as PDF viewer.
