It isn't developed & I don't think there is any effort going on in that

How? Erasure Coding will have BlockGroups not just one Block, whether you
write in a striped manner or in a Contiguous manner, it will spread over
equal number of Datanodes based on the BPP, I am not sure if anything
changes with locality, just by the way how EC Blocks are written.

Erasure Coding in general was developed for storing Archival data, so you
need to figure out how "many" is ok.
