Does anyone do a controlling lpar on 6.1 with power 6 hardware?

Does anyone follow the dedicated controlling lpar when using guested 
partitions on 6.1 with power 6 hardware?
Back on power 4 best practices pushed this.  And I think it was so that if 
you had to IPL EastCoast and that was your controlling partition you'd end 
up dropping WestCoast also.  However if you had Control, EastCoast and 
WestCoast you could IPL EastCoast to your hearts content with no adverse 
effects on WestCoast.

We don't follow this.  However on one box MAIL3 hosts GDI and GDWEB3.  GDI 
is a test lpar and I have permission to IPL that on a whim so losing GDI 
when IPLing MAIL3 is no skin off of my teeth.  GDWEB3 is one of three 
Domino clustered servers in our DMZ so I can rely on the other two to pull 
their weight if I have to power off GDWEB3 to IPL MAIL3.

The other lpar, on a different box, that is a host, hosts GDWEB2.  Again, 
one of three Domino clustered servers in our DMZ.  As long as I don't 
bring down two GDWEB* lpars at the same time, (thus leaving the remaining 
one flying solo), then it's no biggie.
