There's no particular reason other than the names are based on the matching functions in the plugin interface (substituting read/write for submit/retrieve). The 'enqueue' also makes it clear it's asynchronous rather than a blocking write. This is just personal preference though, I don't have strong opinions, happy to change the names to whatever people think is best.

We discussed the camelCase vs snake_case on the first PR. We slightly leaned towards the former since it seemed to be more common in C APIs (CUDA, OpenCL, etc). Again this is something that we can change though.
