I concur - strictness is generally desirable when dealing with data 
integrity.

In this case, the manifest problem was harmless and the data integrity 
was unaffected.  Speaking as an operator and rpki consumer, what I don't 
have good handle on is whether the manifest checks that would be 
required to detect the problem that happened at ARIN would also detect 
actual manifest integrity problems.  If the answer to this is yes, then 
there is no question about whether these checks should be added to the 
code bases that currently lack them.  Otherwise they are a nice-to-have, 
and I'd very much like to see them added.
