Hi - two related questions:

1/ is it possible to access internal txn data from w/i a subgraph handler?  
2/ if not, is this capability on the roadmap today? if so, where can I learn more about it?

I believe the answer to 1/ is no but wish to confirm. (Perused docs, gh issues, forum, discord).

Thanks

following up on my own q here, some networks indeed have access to `callHandlers`: [Creating a Subgraph | Docs | The Graph](https://thegraph.com/docs/en/developer/create-subgraph-hosted/#call-handlers)

unclear if there are plans to help expand to more networks. Seems like blocked by external support based on the below

> Call handlers currently depend on the Parity tracing API and these networks do not support it.
