I completely agree that the user's experience of using a form should be well thought out, and that error messages like "please remove spaces" shouldn't be part of any well thought out form, but suggest that anything is free of trade-offs is absolute nonsense. That `string.replace()`, along with all the others for all the other things your well thought out form does the thought-at-the-time-to-be-right thing with open the door to both bugs and user confusion. It's worth it, but it isn't free.
