I of course agree with most of this. But I would note a couple of things.
First, the miter saw laser actually powers down after a while and comes back on when the saw is next started, so turning it off isn’t critical.
Some of the vacuums have regular use locations, such as by the downdraft table and near the CNC. I think it’s fine if they stay plugged in and ready to use, provided they aren’t blocking any throughways. (In the metal shop, I was actually considering making a post asking people to stop putting the vacuums away completely. There, the vacuums definitely have standard locations, and buttoning them up completely just makes them harder to use.)
And I would note that there is some nuance to “after every task”. If I’m jumping around between machines on a project, I may wait until the larger task is done before returning to a machine to clean it. This is very situational, depending on how many others are in the shop.
But again, these are subtleties; I absolutely agree overall.
