*Emphasis mine*.
This is where I get lost. What time constraints? Naturally, things have evolved over the ages, and not even the most diligent chanters cover what was chanted at every service - particularly during Holy Week - in the early centuries of the Church, when the hymnography was taking shape (the Triodion in particular), so of course, we can't have a six-hour service. Nevertheless, if we're not going to do our part responsibly, diligently, and prayerfully - be we priests, chanters, the faithful - then why bother? Why not just offer 15-minute amended services where we repeat "I Love Jesus" ad nauseam and call it a day? I hate to come off so flippant, but people are willing to waste hours on mindless entertainment, but start getting anxious as soon as they have to spend more than an hour in Church.
With respect to the point you were trying to make, I had to get this off of my chest, because it has become a major pain point whenever I take part in any service.
