if lnd is so resource-heavy and Google-based
there are (were?) unknown bugs causing lnd to be resource heavy. In principle, it should be as low impact as a lightning client written in C, but not at all in practice
I don't know if the bugs are in the Go runtime/compiler, or in LND itself. When I wrote that comment, neither did anyone at lightning labs
what about the rust implementation? Rust is supposed to be a c-alternative ("you can write bootloaders in Rust")
actual rust-lightning is not production-ready last I heard.
I don't really get your issue about the language/dependencies for c-lightning plugins; just don't use any plugin you don't like?
