Was there a public discussion that led to this change? The 'Contributor Covenant' contains this line:

> Other conduct which could reasonably be considered inappropriate in a professional setting

which is essentially a carte blanche for any actions based on 'violation of the code of conduct', especially with the inclusion of public spaces in it's scope. We've seen it being (ab)used many times recently in open-source projects.

Most recently it's been considered legally binding, and the wide net it casts seems to be a huge liability for contributors (not a lawyer, so feel free to school me on this one).
