Hi,
first to say trying to build surefire with Maven 2.2.1 will fail with a
circular dependency...problem (as Kristian mentioned)...so best would be
to require such things not by a README better by prerequisites/enforcer ...
Apart from the README.txt is intended for developers of Surefire and not
for users of surefire...cause they will on the web site and see Maven
2.2.1 / JDK 1.4 ....The don't take a look into the release-source
package....
The requirement for some plugins at the momment: Maven 3.X
(maven-shade-plugin, maven-scm-publish-plugin)...is not a problem but
the compatibility for run-time...Maven 2.2.1 minimum....
The majority of the plugins will currently being lifted to Maven 2.2.1
minimum which implies Java 1.5 ...which for example for surefire it not
the case JDK 1.4...at the moment...
See here:
https://builds.apache.org/job/dist-tool-plugin/site/dist-tool-prerequisites.html
The next level will be Maven 3.0.5 minimum and number the plugins
accordingly like 3.0 as already mentioned...to have a clear line for
users...(Maven Site Plugin already does so...)...

For the record, maven2 does not have precise enough dependency
resolution to handle the somewhat crazy hoops we jump through to test
surefire with surefire itself. So although we're still 2.2.1
compatible, we've required 3.x to build for some time.

Karl, the README.txt will force the users to prepare for Maven 3.
IMHO the SUREFIRE 3.0 would completely switch to Maven 3.
Then we can use prerequisites with enforcer declaring the same min version
of Maven dist.
We will have chance to use Java Generics instead of using java.lang.Object
in public API, remove jdk-1.3 and 1.4 profiles, declare surefire|failsafe
property prefixes, use JDK 6 and Java 1.6 API, and break the backwards
compatibility.
The Java 6 is not maintained by the Oracle. It would be nice to see the
Maven running on the top of Java 8 in the near future. I am not sure if we
would have any bigger benefits from JDK 7 except for NIO and GC
improvements.
