I've been looking for statistics on PDF viewers, but I don't think
such a thing can exist, as I don't see any method to produce them...
It looks obvious to me that noone uses AA 5.05 anymore, but I must say
the TeX world is full of surprises!

I don't think uncompressed PDF 1.5 is useful: most PDF readers don't
even read the version of the PDF, they just try to read it as well as
they can, so practically, uncompressed PDF 1.5 is equivalent to PDF
1.4. But I'm in favor of the option in tlmgr too.

Thank you,
