This is an anti-feature. It does not remove UI bloat. Instead it removes the ability to easily quote an entire block of text, to easily convert a few lines in an ordered list, etc. The toolbar is not just about typing Markdown. It has editing capabilities.

Since you're against adding options, I suggest to just remove that feature.
