Exactly. In this case, memory leaking is not a problem at all. My thinking was that once we do decide to free the
top-levelobject, it feels more consistent and less surprising to also free what it owns, even if the lifetime is
effectivelythe whole process. It’s less about resource pressure and more about keeping the ownership model clear for
futurereaders and maintenance.
TBH, I’ve been very careful about judging whether a memory-related issue is really worth patching, as I asked you about
thisbefore. I think I used the wrong subject line here, the point isn’t about a memory leak at all.
I understand the trade-off, and I’m happy to drop this if the consensus is that it’s not worth touching.
