That's exactly how it works.  By restricting yourself to the official released
version you avoid any new bugs generated by post-release patches but you also
avoid the benefits of bugs fixed by the new patches.  YMMV.  Only a careful
reading of the change logs will tell you whether you need the additional
patches.

On gentoo, they do a fairly good job of screening patches for glibc, so I
usually upgrade a few weeks after the new incremental release is marked stable. 
Unlike RPM, I haven't encountered any deficiences thus far, and gentoo does use
bzip2 for source distribution.  OTOH, almost nothing is distributed in binary,
so maybe the source level packages are less picky.
