I think sometimes the migrations were halted more because MSFT wanted to hold off. Microsoft makes more money selling Azure outside the company, and they needed more power for GPU build-out once LLMs and AI started becoming one of Microsoft's Things™.

That said, the difficulty of the work was absolutely also a factor in deciding not to carry through with earlier migrations, so your point still stands as a whole IMO. Just, now solutions will be found for blockers and engineers will be kept on it, rather than efforts stalling out and being put on hold.
