I don't know about vanilla emacs (because I don't use it), but when using emacs in evil-mode, you can record a macro to a register and then edit the register. That way you can correct your mistakes. You can also append to registers and combine registers, so you can continue recording macros where you left-off.

Since evil-mode is a vim-emulation mode for emacs, the above is possible in vim as well.

You can dump your macro to elisp without difficulty. That isn't the problem. Keyboard macros are at their best when you get to use all the regular keys that you normally would, so that you can reuse everything you already know, without having to learn a whole other set of commands. Both editing the resulting macros, and needing to treat C-g as fatal, break this.
