Your method makes more sense to me.
The need to gatekeep a genre which - by now - I reckon has far more entries that don't match the definition of a traditional/classic rogue-like game just seems unnecessary.
Giving a qualifier to 'roguelike' to delineate the classic versus more flexible/modern style makes more sense.
Does anything in the world ever get under your skin?
If yes, then extrapolate that feeling to these situations and try to understand that just because it doesn't upset you, doesn't mean it wouldn't upset someone else.
If no, then I guess I envy your care free life but you'd do well to try and understand that not everyone is as lucky as you.
