According to https://insights.penumbra.zone/, Celestia’s native token (TIA) is one of the most popular assets in the shielded pool. In fact, it is has the third largest total value shielded behind two heavy hitters: USDC, and allETH.
TIA is bridged using IBC, and as such, benefits from light-client security and has no canonical representation competitors. Since the asset is popular, canonical, and securely bridged, I think it would make sense to add it as one of the gas tokens of Penumbra.
Anecdotally, I have seen a lot of usage of Penumbra by the Celestia community. First, during the Mammoth NFT mint, and later in various ways or another to custody assets. Adding TIA as a gas token would make life easier for future users, letting them deposit and withdraw from the shielded with minimal friction.

If people have specific technical questions about the protocol , I’d be happy to answer them.
