The moment you append e the value of APR_BUCKET_NEXT(e) changes to your
context brigades sentinel.

Yes and no. You can have multiple brigades and only the last one holds
_the_ EOS bucket.

That depends, but usually you will use it. ap_pass_brigade is misnomed.
It passes the buckets held by the parameter brigade to the next filters
brigade. Alternatively you probably could append to the next filters
brigade.
