@Riot Spectator's Delay for Custom Games

I'm not sure who to direct this to, but I'd like to know what exactly is the reasoning behind keeping a strict 3-minute delay when spectating custom games? I understand having the delay in place when spectating any other game type to avoid ghosting, but what about customs?

I ask this because the LoL club at my university just held a 1v1 tourney last night, and while it was a super fun event, it was kind of lame having a 3-minute delay on every game played. We would have much rather watched each game live.

Could there be an option to adjust the delay time in custom games to the game creator's preference? This could still allow the game creator to implement delay if they choose to, but would also allow other Informal tourneys to feel more "live" with the option to have reduced delay.
