Even when explicit, many GMs ignore difficulty mods...
EG: FASA STRPG 1E... It stated routine tasks were 1d10, only unusual actions required rolling 1d100 vs the skill. Yet, most GMs seem to have ignored that...
That's why I say it needs to emphasis positive mods much more strongly in most games; its really easy for GMs to end up using the default difficulties (which are usually intended for use-under-stress cases at least) for things they aren't intended for, and thus make either the world seem much harder than it should be or the characters much less competent than intended.
