It definitely depends on a few things. Most importantly: do you want to? If you don't want to, then don't do it, this isn't a business critical application that hundreds of other engineers will work on. Another consideration is: how much more work on this will you do? If you think that a rewrite will be good because you (and potentially others) will be modifying the code quite a bit in the future, then maybe it's worth while. If it's a project you consider finished and would rather work on other things, then do that! If you really want to, you can always clarify design decisions (or lack there of) at the top of the README.
