Massive wasting of time? I feel like you only read half of that sentence. entr to run commands on modifying files/directories Alt-Tab to the command console that I always have running. plain Makefiles to run your code I have no idea what the advantage is here. F5 to run my code, including scripted deployment. LSP and alike tools for your language I don't know what this means.
