I understand your point and what you're trying to accomplish, but you have to see that this does more harm than good. The vast majority of complex edits, such as adding tables, are done on desktop devices. So sure, it might encourage edits to be more mobile-friendly, but it discourages desktop editors from engaging in the site. Fewer desktop editors leads to fewer complex edits. You might look at the situation and say, "we must force editors to make mobile-friendly tables!" but I look at the situation and say, "either the tables will look poor on mobile or they won't be there at all."

Making the entire site look like a mobile phone will just discourage desktop users from using the site. That would be fine if you wanted a read-only experience, but we want to encourage users to edit. They're not going to edit on their smartphones because touchscreens aren't convenient for typing out long strings of text, and right now, they're not going to edit on desktops either because the desktop interface is so clunky and... well, ugly.

EDIT: I just want to say that even if we disagree, I really appreciate you engaging with us.
