Doable now?

[EthnTuttle]

Is this doable with libsecp256k1 as is currently?

[jonasnick]

There's a module in libsecp256k1-zkp that provides half-aggregation.

[EthnTuttle]

I assume this means full aggregation is still lacking?

[EthnTuttle]

I suppose a better question would be: is full aggregation being worked on anywhere? Is there a reference document or something I can study to better understand it?

is full aggregation being worked on anywhere?

Not that we're aware of.

Is there a reference document or something I can study to better understand it?

https://cisaresearch.org/ is the best resource for getting started, but there's not much more on full aggregation.
