The language also takes backwards compatibility very seriously, anything that goes into std "must be maintained forever". It is also argued that a large stdlib means the maintainers have less time to work on the language itself.

I understand not every language can have Go's amazing stdlib, but I would much prefer Pyhton's approach where every now and then some package/function from the stdlib gets deprecated/removed. Rust's 3rd party ecosystem is the worst thing from the language, worse than the compile times.
