Should someone run a signal through a preamp, Elektron Analog Heat, Empiracle Distressor, cheap mixer, and so on and so forth? So many options. They will all add some shade of color. Certain preamps add a flavor, and some of it may be subtle, but when running all tracks through these preamps, all of the subtlety adds up and gets a nice cohesive sound to it. Some would call it the sound of a console. Whether or not you want, or even need that for your music, is entirely up to you.
A while back I ran some synth bass through a DI into a Neve type clone. It sounded very nice, nicer than the dry signal. But again, it is up to you or not. So much great music has been made on nice consoles, and an even greater amount of music has been made without the need for nice consoles.
Be the artist and pick your color.
