Lengthy load times are detrimental to UX. Just look at how people are increasingly less likely to wait for a page to finish loading with every additional second it takes to load [1, 2].
In regards to feedback from users, this is especially true when finding product-market-fit (when an idea actually becomes a business). There’s nothing better than learning what customers who actually use your product want in future releases/improvements. It’s a case of building based off actual demand versus based off a hypothetical in one’s mind (a very common “failing”, i.e. learning experience, for first-time founders). Only when your product grows to the point of attracting potential customers outside your target demographic should you not place tremendous value on every single piece of feedback.
