If ya think about it, something like Explosions in the Sky isn't terribly different than some p&w....maybe more distortion and lingering on a minor key with p&r (post rock) with more singing and major keys with p&w. Both p&w and p&r like a big cathartic chorus.But really, I play p&w and post rock so...
I kinda disagree.It covers up your inability to play

To add to this, I believe spring reverbs were added to organs so they could emulate the reverberant spaces of churches. From there spring moved into guitar amplifiers and/or outboard units in the case of Dick Dale, who was arguably the most important early guitar player who made reverb part of his signature sound.I'm going to go all historical on you and say that reverb is the original musical effect and is in fact largely responsible for the development of the music we have today, so it's very natural that guitarists would use it as well.
To specify, musical harmony progressed very closely with the development of architecture in the west. As we built larger and larger halls, the reverberation got longer and longer. What this means is your previous note is literally still playing when you begin your next one and, as a result, the choice of your next chord has to be something that makes harmonic sense with the previoua thing you were playing.
Nowadays, digital reverbs are the next progression beyond gigantic halls and we can get even longer reverb times than ever before and we can now manipulate the decays of those reverberations unlike any other method allowed in the past. This inevitably leads to different types of music coming about.
Generally speaking, though, if you have a perfectly dry guitar amp in a dry room, your audience will tend to actually understand your chord progressions less on a gut level because the previous chord dies out before you change to the next. Of course, this is desirable for more percussive based music as it's the rhyhm that is the focus and reverb actually obscures that.
