It is more like "fearing someday we might modify the callees and
they may start returning error codes".
Admittedly, "someday" has a tendency not to come, but making the
callees void and changing the callers who are already checking
the error codes to ignore what are returned from them somehow
feel backwards and pushing that someday further into the future.
Either patches to implement the error checking in the callees,
or arguments that particular callees the series touch do not
have reasonably graceful error return path are welcome (the
former advocating against and the latter advocating for the
application of the patch).
