Would it be difficult to add a 'rename from scratch' feature? I mean a feature that takes normal code (as opposed to minified code) and (1) scrubs all the user's meaningful names, (2) chooses names based on the algorithm and remaining names (ie: the built-in names).

Sometimes when I refactor, I do this manually with an LLM. It is useful in at least two ways: it can reveal better (more canonical) terminology for names (eg: 'antiparallel_line' instead of 'parallel_line_opposite_direction'), and it can also reveal names that could be generalized (eg: 'find_instance_in_list' instead of 'find_animal_instance_in_animals').
