It doesn't grow like that in my experience. I just loaded the source for Luarocks on Sublime Text and my RAM usage while browsing some Lua code in it is 31MB, pretty decent. If you're doing Lua, there is always Zero Brane Studio (https://studio.zerobrane.com/ https://studio.zerobrane.com/) which is built with Lua and very nimble (uses wxLua which is wxWidgets + Lua), unfortunately it is not playing well with my hidpi screen. Another good option for Lua developers is TextAdept (https://foicica.com/textadept/ https://foicica.com/textadept/) which has wonderful support for extending it using Lua, IMO it is like an Emacs but with Lua. Those editors are available as ia32. I didn't succeeded in compiling ZeroBrane studio for arm64 even though I managed to compile both Lua and wxWidgets for it. As for TextAdept it uses GTK and that is not available for Windows on ARM. For the past week I've been using sublime text and am quite happy with it. I also use VSCode when I need some more intelisense help.
