So about the argument that it's less content for newer players. The current state of things is less content for ALL players, as people are less inclined to map these maps that are 4:30min long if they have to spend that much more effort compared to extending the song to 5min, or just mapping some other song.
Doing something like this would give more incentive to map these longer maps for mappers who would maybe otherwise not map these songs at all, or greatly increase the amount of songs they map in this length range.
As for the details, it's obviously something to discuss in terms of what would be appropriate cut-offs, limits, appropriate spreads (would EHX be acceptable for example) etc., but I don't think it's a bad idea overall to suggest something like this.
As for the "too long to require a diff for you" thing, that already happens with approval maps, and as more people go with extending songs, or cutting them down, you're still not getting the required diff for low level players in the length range that is being discussed.
