No problem, I can change that myself.

Due to the changes in latex 0.95 there may be a problem with LaTeX packages supporting only >=0.95 in the future. Thus having Luatex 0.95 in TL 2016 should be future proof.

I do use context but I probably can get the binaries from context garden.
The TeX Live version will be out of date when the DVD is released.

I can still update using tlmgr (and there will probably a way to get from 2016 to 2017.)

I use Macports for recent versions of Perl, Python and Ruby.

I have to run tlmgr to see whether PGP signing is supported on PPC.
The intel version asked me about that.

TeX Live can be used quite a long time after its expiration date.
(Just look at Linux.)
As long there is a way (hack) to get more recent packages there should be no problem.
(And there is still texmf-local / ~/Library/texmf)

I’ll have to replace the PowerBook in the near future.
But as long it is still running (walking) I see no reason to spend >1000 € on something that will probably not last 12 years.
