You titled the thread "marked for deletion" this proposing that we implement pretty much the same idea in dCore. And that is what I did, with the difference being that the lst and dep files are left by default, as I sometimes do re-import things and like to keep that data. You want it to be removed, so I said lets give an option to purge.
Since folks who try dCore will be coming from Core, I don't want them to have to learn an entire different way of doing things besides using importsce instead of tce-load.
Anyone here knows that I always listen to feedback and cooperate with whoever who posts here. All ideas brought up here have been implemented unless there is a good reason not to.
If folks want to leave the .lst and dep files there by default, rather than remove them, say so here. I can easily change it to remove them by default, and will do that, giving a -k option to leave them.
