wal_init_zero / wal_recycle

Hello,

while searching the doc to solve an issue, I found the interdependency between those 2 parameters was not obvious.

Here:
https://www.postgresql.org/docs/14/runtime-config-wal.html#GUC-WAL-INIT-ZERO

the wal_init_zero set to ON cause new WAL files to be filled with zeroes.

It was not crystal clear to me that when wal_recycle is also ON , the recycled files are not filled with zeroes, because they are not considered as new. Could we add a sentence stating this?
