In reply to redata425.

Really appreciate you weighing in. As I tried to say, I think if you're a developer comfortable with it all and running it all top to bottom forever, go all-in on Composer, Capistrano, or whatever tool lets you breathe easier. Your endorsement is genuine and convincing in its value for you.

It's the in-between cases — where a developer sort of thinks they should be using fancy stuff but aren't comfortable yet, where they're going to leave the site to a non-technical owner, etc — that I was trying to explore. There are a lot of those sorts of situations in the WordPress world, and their place in a discussion of "Composer: yes or no?" is probably most appropriately a "sometimes yes, other times no" answer. That's where I was trying to get to.
