Yes, definitely, I'm currently looking at the testing framework. There 
already are tests for most of the cases in dbManagerLimits.java, but we
probably need some more...
Documentation: this page would need to be changed...
http://incubator.apache.org/derby/manuals/reference/sqlj268.html#HDRIDLENGTHLIMITS
Is the documentation in svn somewhere?

No known implications, but as always there might be a bug in the patch 
or it might not be possible to increase some of the identifier to 128
because they are limited by the implementation. --> 1) tests are REQUIRED!!!

Yes, I this still applies: There are always issues if you migrate 
to another database, the only difference is, that you couldn't just put
the sql dump into db2 anymore if you use longer identifiers.
