Aliases as a feature are meant to save you typing in the first place.

The more you use aliases, the more you save in typing, over time.

If you can't remember a particular alias, that means you have a use for it very rarely (spaced repetition and all that), and the benefit of having it around is very low anyway.

I generally try to prune my bashrc from aliases that turned out not as useful as I thought. I have about 50 atm, and don't feel the need for a helper tool.

Maybe if one's aliases skew towards a particular pattern this tool could be useful, I don't know.

I keep those rarely used ones in there as a useful record of the syntax that I created the alias to get around in the first place. Fish shell's abbreviations are even more useful in this respect as they expand to the full command.
