I am not sure that we have any reasons to be that aggressive about
this one either, and this would mean that wal_compression=on implies a
different method depending on the build options. I would just stick
with the past, careful practice that we have to use a default
backward-compatible value as default, while being able to use a new
option.
If we think this new thing is strictly better than the old thing, then
why not make it the default. What would be the gain from sticking to
the old default?
The point that the default would depend on build options is a valid one.
I'm not sure whether it's important enough by itself.
