Has anyone realized that by disclosing the existence of “US Task Force Ayungin,” Biden admin implicitly recognized Philippines’ sovereignty over a disputed SCS feature?

Washington has never taken a position on SCS territories(but it has in ECS). This is a clear signal to China.*

South China Sea: US troop aid may reassure Philippines but will prod China, analysts say (archived)

The Philippines has said the US task force only offered support – in the form of intelligence and surveillance – and did not directly take part in its resupply missions to BRP Sierra Madre, the retired warship, but analysts suggested that China’s leadership could see it in a different light.

…

Zheng said the revelation about the American task force meant the US was likely to be more engaged in the drawn-out maritime conflicts in the region, even suggesting that Washington would “be the first to take part in the command and planning of Philippine maritime activities”.

…

Ding Duo, deputy director of the Centre for Oceans Law and Policy at the National Institute for South China Sea Studies in Hainan, said the presence of a special task force showed that Washington and Manila had long cooperated on resupply operations to Second Thomas Shoal.

…

“Such support emboldens the Philippines and is not conducive to China and the Philippines managing their differences,” Ding said. “The US involvement has also squeezed the political space for internal coordination and decision-making within the Philippines.”

…

He said it was also possible that American troops could be on Philippine ships and involved in front-line action “using a covert or concealed identity to participate in Philippine maritime operations” in future.

He said the US could “only intervene [in South China Sea disputes] in a covert manner and so it took the form of a task force”.
