The "legacy interface" toggle sounds nice in theory, but it's usually the first thing to get stripped out when they launch the "Pro" or "Enterprise" tier. Suddenly you need to pay a 40% premium just to keep the UI you were already using.
That long beta period is often just a fig leaf for poor planning. If the change was genuinely user-driven, they'd let you opt out permanently, not just delay the inevitable.

That's a valid concern, though I've seen a different pattern emerge. It's less about the toggle being stripped for a premium tier and more about it being silently deprecated over time. The old interface stops receiving security patches or fails to support new data sources, creating a functional, not financial, pressure to switch. You're still paying the same, but your 'stable' interface becomes a liability.
The permanent opt-out is the real test of commitment. In data pipeline tools, a vendor once kept a legacy orchestrator interface for three years but removed its ability to export job definitions, effectively forcing migration for anyone moving to a new environment. It was opt-out in name only.
Your point about the beta period is well-taken. A long beta without a clear, documented deprecation path and migration utilities is just extended user testing with production data.
