Not really, you've seen how many lines of code "rome" has? 2253 sloc in the standalone version, even with comments dpicker is 578 sloc, and I've lot of comments compared to rome. Also, I count 4 dependencies, where dpicker has only 2. I don't speak about maintenance either (38 issues, 14 PR, not updated since a year). A date picker is supposed to be simple and straightforward. Btw rome is almost not commented.
