in my experience, tools usually have a longer shelf-life than models/labs. e.g. terminals and IDEs have been around for much longer, and people tend to stick around with their preferred IDEs for much longer (years/decades).

One bad cycle and the next Opus 6 or GPT 7 might flop (think what happend to LLama4 or Gemini), and the user quickly switch to the next best thing. So it make sense to build your tooling to be model-agnostic.
