Either way, it's a trivial algorithm to implement. Calculate len("function_with_lots_of_arguments("), add that many spaces after your indentation tabs on the next line, continue arguments. The fact that editors/auto-formatters don't do that speaks far more to their lack of desire for that code style then it does to the difficulty of doing it.
The simple fact remains that using tabs provides many accessibility benefits that spaces are just unable to provide, like being able to drop tab size when you boost font size (legibility for poor vision) so your code doesn't indent off the side of the screen, or far better support for indentation for proportional fonts (another thing that people swear by for increasing legibility).
