Good question.
The liquid staking module is core infrastructure that serves two purposes
(1) Improve the liquid staking UX
(2) Add liquid staking regulation to the base layer
My opinion is that adding LSM to Celestia is orthogonal to the rest of this post. It comes with its own set of benefits and tradeoffs, but isn’t necessary for networks to support liquid staking (Stride provided stATOM for almost a year before the Hub added LSM).
Given the complexity of the module, it’s not obvious that Celestia should add LSM to the base layer (a core value of Celestia is to keep the base layer minimal). It also hasn’t been upstreamed to the Cosmos SDK (to my knowledge), so Celestia would need to run a Cosmos SDK fork, which would require an involved CIP and engineering work. These costs would need to be weighed against the benefits, which feels beyond the scope of adding ICA on an accelerated timeline to enable safer and more aligned liquid staking in the short-term.
