Fair point about process bloat. Just to clarify: I'm not an ADR expert nor do I personally know Harmel-Law. Just deriving insights from his blog post that I linked to earlier because I thought it was interesting.
But, I think you might be picturing ADRs as heavier than they need to be. Most changes seem like routine updates ("We decided Postgres" → "We're migrating to Aurora") that go through normal code review. The big architectural shifts that would trigger Security/Compliance review probably should anyway, ADR or not.
The key insight is that ADRs document decisions, they don't create them. If a change is big enough to need committee review, it likely needs that scrutiny regardless of whether there's documentation.
The alternative, undocumented drift, often creates much longer delays when people rediscover decisions during incidents. Curious to hear from folks who've actually implemented this at scale, though.
