Lakehouse is an architecture defined to overcome the limitations associated with an immutable object store. It is already in my eyes introducing unnecessary complexity (i.e. at which point do I just need to transition to a proper database, even for larger scales (that cannot be accommodated by a database?), when is a tiered data architecture with stream materialisation snapshots actually simpler to reason about and more economic etc.)

I would hope that S3 could introduce a change in the operation of said fundamental building block (immutable object), rather than just slap an existing downstream abstraction. That's not what I call design for simplicity. As an external observer, I would think that's internal amazon moat management with some co-branding strategy.
