Looking for suggestions π€

I'm building date-fns MCP. I'm starting with documentation (per function doc, vectorized search) but have many more ideas.
What would you want to see in it?

I will create @date-fns/react with hooks to quickly render dates, ranges, distances, etc.

Should date-fns accept strings as arguments? I will abide by the results of this poll.
For context - we removed strings in v2 to avoid bugs caused by engine differences and parsing time zone nuances.

Accept strings

Rare moment when the US date format makes sense
7 Jul 2023
Today's date is written 7/7 in the USA. It's also written 7/7 everywhere else in the world, because that's how dates work.
This pattern will repeat 5 more times this year, and 12 times in 2024 and every subsequent year.
It only happens once per month.
