The problem is (and this problem does not originate with TL)
is that all versions of PDF use the same file extension
(.pdf), and on any given system, that extension can be
conveniently associated with at most one utility).  Thus
I (and others in a similar position) would either have
to re-associate PDFs with a more recent version of AR,
or leave the association as it is, with a more functional.
less crippled (but also less modern), AA.  It /may/ be
possible to create an alternative action (say, "Read" :
the default is "Open") but whether TeXdoc could conveniently
attach itself to the "Read" hook rather than the "Open"
hook I could not predict ...
