If you're thinking about an edge where you have less than 3MB of storage space, and likely very limited in-memory space, you'd probably still be better to go with C. These kinds of environments are becoming very small % of use case over time. Usually such resource-constrained devices & systems have their own build system or crutch libraries built in to help reduce binary sizes to this scale. It is against golang's design principle to make a language that requires external frameworks/libraries to run. As it is, you can build your golang app, send it over an ssh tunnel and have it running on the remote system without much thought at all.
