The type system complaints are somewhat in the area of "it should be more like Haskell", but the debugger, heap profiler and thread debugger ones are certainly not. Golang has extremely basic tools for anything beyond formatting/compiling compared to most modern languages. This is just a limitation of the current ecosystem, not something you can say has tradeoffs (except of course for the Go team's time/prioritization of features). Delve is getting better, but it has a LOT of ground to cover before it is half as useful as gdb or a java/C# debugger. Same goes for the profiling tools, especially on the CPU side.
