It is better that we split 'protect' right rather than using '$wgCascadingRestrictionLevels': 1- 'protect': Change protection levels 2- 'editcascadeprotected': Edit cascade-protected pages (exactly like 'editsemiprotected' and 'editprotected' rights) Change protection levels and edit cascade-protected pages are two different concepts.
And what makes you feel 'editprotected' would be inappropriate for this purpose? Cascading protections are still protections, not something different level of protection.
Because 'editcascadeprotected' can be temporary. For example now (August 16) you can not edit "Wikipedia:Selected anniversaries/August 16" on en.wikipedia, but you can edit it on other days. So 'editprotected' is not like 'editcascadeprotected'; a user with 'editcascadeprotected' right should not be able to edit all protected pages like 'editprotected' right.
If you can edit cascading-protected pages, you can protect arbitrary pages by transcluding them in cascading-protected pages. This makes it equivalent to protect anyway, so there's no reason to split the rights. WONTFIX. (And I think this is also a duplicate of something, though I'm not sure which offhand).
