That's not the way I understand the "-less" composition they use. "harmless" doesn't mean "poses less harm", it means "poses no harm". "colorless" doesn't mean "less color", it means "no color". And so on. So to me, "suckless" means "doesn't suck", no humility. Admittedly, it doesn't exactly follow the normal composition rules so the exact interpretation is more up in the air, but that won't change the fact that many people will read it the way I described above.
