Thanks for the feedback! This was a Duelling Access Needs™ change -- somebody else found "custom" alone really hard to understand. ("Custom what?") I've changed it again to make it a little clearer ("custom filter" instead of just "custom" -- the issue was not specifying 'filter' or 'access filter' as the noun going with the adjective 'custom'.)
(Sorry about the unexpected change, too -- changing what the site text says is a different process than changing how the site behaves, so it doesn't fall into the usual "changes only at a code push". We tweak the site text occasionally based on suggestions and feedback.)
The change does only apply to the original update page -- the beta update page handles choosing security levels differently, and (IMO) in a way that's much easier to understand and distinguish.
