Embedded LND vs LDK Node | ZEUS Documentation

A comparison of the two local wallet implementations available in ZEUS.

I do appreciate that they have a 3rd party FDroid repo, so that's a point in their favor. I take it they're not qualified to get included in to main repo? I know that requires using 100% open source libraries, which is a standard that many "open-source" apps still fail to meet.

TY. Is there an expectation that LDK might get some of these features in the future (e.g. be able to backup to a file instead of auutomatically putting backups on some remote server), or are these inherient limitations based on the design?
