Walk through any branding showcase from the last five years and you'll see the same pattern: every logo collapsed into a sans-serif wordmark with extra letter-spacing. We're told this is restraint. Most of the time, it's avoidance.
A logo is a chance to encode what you stand for. Strip too much away and you're left with a typeface anyone could use. That's not minimalism — that's withdrawal.
Restraint earns its keep when there's a strong, specific idea underneath it. If your wordmark works because it's quietly confident in what it represents, great. If it works because it doesn't say anything, you've made yourself harder to remember on purpose.
