This is mostly a question, but I was wondering what's so special about 512b number? Looking at some of the open/closed issues it seems you are attempting to fit an entire website (lib + css + app) in the MTU size (usually 1500 bytes). But I have no idea about iot devices, and I'm trying to figure implications of exceeding 1500 bytes.

Any pointers that can help me wrapping my head around the size limitations?
