those commits -- it's not just them. That means that the pari in sage is
neither compatible with upstream's 2.5.3, nor with the upcoming 2.6.0.

practice.
I'll have a shot at that one but it's probably nothing new to you. It
depends on the trade off. Backporting in a distro like debian that is
keeping fixed version of the software has much as possible is good.... so
long as you preserve API. If the patch breaks API that means potentially
all dependencies will need patching for the new API. So the trade off is
between the number of dependencies you have to patch for the new API and
how badly you want/need the backport.
It applies also to sage but the scale is a priori less than in a full
distro. In the case of pari in particular, I don't think the list of
dependencies (especially dependencies not in sage) affected by your change
is very long (make that non existant until proven otherwise).
Debian my have enshrined the above discussion in a precise policy but I am
not a deban-er.
