There is certainly no reason to assume that a majority of potential
TL users will still be using AA (or, more likely, AR) 5.0.5, but
we have no idea what fraction are, nor what fraction are using
non-Adobe software that cannot handle PDF 1.5 with the proposed
compression.  Thus unless there is clear and indisputable evidence
that (say) 98,5% of TL users can handle compressed PDF 1.5 w/out
any difficulty, I argue that we should continue to (a) supply TL
documentation in PDF 1.4, and (b) that TL should be installable &
subsequently configurable to generate (at least) PDF 1.4, uncompressed
PDF 1.5 and compressed PDF 1.5 at the user's choice.
