Back when I was doing client work for a small agency we would get requests for these contact forms that would have 30+ fields, often many of them required. The forms made strong assumptions about why you were contacting them, and if you did not fit that mold the form was particularly painful.
No one wants to take the time to fill this out, you are losing business.
I would always try to talk them into simplifying. All anyone really needed was Name + Email + Text Area but many were insistent and many of these nightmare forms got built. I genuinely wish I had stats on how many people landed on the forms vs actually filled it out.
The worst part was that the vast majority of these just converted into emails to the owner of the small company with no backing database, because we charged extra for that. You'd spend all that time filling out all those fields and they would get concatenated back into a single string (with new lines and field titles).
I'm reminded of this when I try to submit an issue on some of these GitHub repos with wildly overdone templates. I just want to let you know you have a broken link in your documentation but you're forcing me to fill in my OS and build version and last time I went to the dentist and sign a CLA... and I've just not bothered more than a few times. Enjoy your broken link.
