Summary: X-link: meta-pytorch/botorch#3146 Simplifies the get_task_value_remapping() API from 4 parameters to 2, addressing confusion reported in facebook#3085. The observed_task_values parameter is removed because the parent diff (D90769576) now makes MultiTaskGP track observed/unobserved tasks internally via _observed_task_indices and _unobserved_task_indices. The default_task_value parameter is removed because the previous behavior—silently mapping unknown tasks to an arbitrary fallback—was confusing and error-prone; instead, unrecognized tasks now map to NaN, providing an explicit error sentinel with a clear warning message.
