You seriously think VS Code is bloated? It's always super fast for me, not even noticeably slower to start than notepad2!
I'd way rather my programming editor be flexible, hackable, fully support unicode, and integrate with my workflows. When I need a hyperminimal editor I have vi, which the confusingly named CudaText is much larger than but not substantially more powerful at editing with.
Executable size comparisons are either an important part of managing core OS primitives or a complete waste of time.
It's 2017. You can keep an app open, you can open more than one at a time. You can use different tools for different things.
