I understand your way of thinking, but we ended up having a flow for a government site where users had 2-3 steps what normally could be done in 1. Also many were not tech savvy and confused. So we ended up adding JS to automate the click.

You automated a click on a government website? So tell me: how'd that audit go?

This depends on your willingness to turn away business, and may not even be legal depending on where you work. In the United States, I would not want to defend that copy and paste scheme as being compliant with the Americans With Disabilities act having seen usability tests from people trying to accomplish that exact workflow using screen readers. Remember that things like cognitive impairments count and, like vision and motor control/range of motion, most of us will be affected at some point in our lives.

What I do think would be reasonable is having a well-labeled link which takes you to a confirmation form: someone can follow it easily and choose to submit it with far less friction and it leaves standard web semantics intact.
