I can't dispute the upstream disappointment, but the obvious benefit is
enabling uprobes for systemtap.  There are a growing number of packages
building in markers with systemtap-sdt-devel for debugging and tracing,
so they will expect a way to hook into these.  Yes, the impending
inode-uprobes will be sufficient for this case, but it's a step
backwards in other respects as well.
