Review Comment:
I'd argue its worth doing since more/duplicated code => more opportunities
for bugs to slip in when updates are needed and more for a future developer
(maybe us) to understand ([code is a
liability](https://blog.devgenius.io/code-is-a-liability-to-developers-e6ffade2b7d0)).
I'm not going to block on it though, its not very important
