One way this can be a bit easier is you can put the default in the extlookup
call itself so it does not require someone to update a separate defaults file,
but just to write the correct lookup. This makes it less likely to blow up (but
certainly doesn't prevent it)
For example:
$vpnaccess = extlookup("vpnaccess", 0)
case $vpnaccess {
'0': { $role_vpngateway = false }
'1': { $role_vpngateway = true }
}
This tests for the default value and also does the 0 => false conversion.
The case this doesn't work for is when you really want the variable to not have
to exist, so you can use a variable if it exists, or ignore it if it doesn't.
But it does handle some of the cases.

I agree this is useful, as I've run into the same problem lots of times,
