Unfortunately, there's little point in purchasing and migrating to a software offering that is stabilized and being supported "for now". ALC is way overkill for the need and an Eclipse interface is not a realistic option compared to a web interface for a management persona (as opposed to a developer persona).
Neither is developing a customized solution using the API for the sole purpose of providing an interface (the customer is trying to get away from customizations, not develop more). NXBridge "might" be an option but I'm personally not comfortable relying on 3rd party vendor interfaces (anyone else remember Fastlist and Fastedit?). It's arguably just another form of "customization" and tends to introduce upgrade and support challenges... and wasted investment if/when CA decides to deliver the functionality themselves.
What I might suggest and support is CA reconsider/modernize providing "Endevor Workbench" (the pieces of CMEW without the Harvest hooks) and just ship that as part of the Endevor base product. Now THAT would suit my persona perfectly... Even just stripped down for Package views....
I guess I'm going to have to wait for the "there will be more shortly"....
