Now you're just being silly, Darren.
Judging whether or not something is a roguelike by manner of checklist is pointless, since checklists (unless defined really well) lack flexibility and will become outdated sooner or later. It IS an evolving genre and standards will shift with time. No point comparing new roguelikes strictly to Rogue/Hack/Moria to see if they're "valid".
However, I expect all of you know what is meant when someone here says roguelike.
There's this arbitrary fad to put the roguelike label on things that merely applied roguelike design philosophies to a completely different genre...
Realtime games (platformers, first person shooters, rtses, action adventure games) are increasingly likely to be called a roguelike if they incorporate even a single element that roguelikes are known for (some randomness, "hard difficulty", random level generation).
Is the roguelike genre so empty/desolate in your* eyes that we have to desperately start calling completely unrelated games (Borderlands/Dark Souls) roguelikes?
I, for one, have tried to keep my hands clean especially of calling things roguelike-likes. Fuck. Just say "This game has some design elements that were inspired by roguelikes." instead of calling it a roguelike-like and thus entering it into the roguelike family tree next to roguelikely, 3rd cousin removed from rougelike etc etc.
As for myself, when I see a game I just label it a roguelike, a [closely related departure from roguelikes] or [game that just so happens to have some randomly generated things in it].

If I hacked Brogue so that it let me restart the level when I die would Brogue then not be a Roguelike anymore?
It'd be something along the lines of turn-based dungeon delving RPG with a lot of roguelike influences. But it wouldn't be a Roguelike anymore. Permadeath is one of
the core features, in my opinion.
