Reading the IBM page[1], a must read if you haven't already done so, it 
seems they do have a switch to control this, albeit a temporary one. V5R1 
will ship with a data area QUSRSYS/QLILMTLIBL, the existence of which 
prevents more than 25 libraries being added to the user portion of the 
library list through any of the interfaces affected. The release after 
V5R1 requires you create this yourself, and after that it will have no 
effect. It does give a bit of breathing space, but as Al points out (in 
the snipped out section from above) it's not very comforting if you don't 
have the source :-(

Our company has been fortunate:
- we have the source code for the majority of our applications, with the 
others covered by maintenance agreements.
- we have a cross ref tool (in our case Hawkeye) that can identify uses 
of RTVJOBA and the various API affected.
- it turns out we only have a handful of routines that needed changing, 
and I was able to make them V5R1 ready yesterday.

It is a fairly insidious change though - I need to post an update to one 
of my open source tools (CHKLVLCHK) now, as it's among the handful 
affected :-(
