which default? If you don't want to change the check commands, what else? 
Looking into your patch indicates you want to change the check commands.

Maybe thats you POV, but I know a lot of people who just want to have the 
transport layer encrypted and they don't care (much) about the certificate 
itself when using SSL.

Forcing the people to edit the default check (files) leads them into the 
problem to migrate all changes in the config files provided by the package. 
This is really annoying, even more if it is caused by a change by package 
maintainers, which is forcing them into this step.

As argued above, this may be the case in your environment and I understand 
your problem, but actually I think the disadvantages for the most of the users 
is much bigger.
If we can find a solution, which doesn't force (potential most of) the users 
to change the default checks, it will be fine. Actual I don't have such a 
solution in mind unfortunately.

I think I will tag this bug "wontfix", so it is visible to others ... if 
anybody comes up with a good solution and/or there will be a reply flood from 
others which also want to have validity checks enabled by default, we have to 
look into it again.

With kind regards, Jan.
