People tend to fixate on bike fit and other things, sometimes ignoring practical considerations like health. Providing yourself with a very upright position on a bike can have enormous benefits if, for example, you have a bad back, prone to slipped and/or herniated discs. In consultation with a chiropractor who is also a cyclist, I was told to get myself as upright as possible. The bent forward position works to alleviate pressure from some backs, but not mine and I was told in no uncertain terms that my bike fit was hurting my back, but that I didn't need to stop bike riding. You often don't need a new bike, or someone freaking out about your bike fit (if they're not your chiropractor), you need to adapt what you have to allow your body to be healthy. I don't know if OP is driven by health concerns, but there is nothing wrong with someone wanting to tinker with their own equipment to suit themselves.
