Not just stylistic choices - I absolutely love the way ex. gitlab lets you do a suggested change in a comment, precisely because it lets me do all the work and the MR owner just has to click to accept if they agree. That lowers the bar for what I'm willing to bring up in the first place (though I personally still don't like to comment on matters of style or taste) while making it less work for everyone, which makes it much easier to give useful suggestions:)
