Is there some additional context on this PR? Was there an issue where this was previous discussed?

We are trying to index erc725y metadata. This allows retrieval and verification of ipfs and https and arweave URLs (this is probably now possible natively) decoding erc725 data is really hard to do in assemblyscript and we have an available module is rust, go and typescript. In addition there are some tools to read big endian numbers. One problem we have right now is erigon which is required for trace_filter does not allow one of our expensive static calls making the index currently fail ... to index the LUKSO layer 1 chain.
