One column, two column layout option suggestion

Why is the layout option of one or two columns not available when you set the front page to be your latests posts? I ran into this when I made a child theme for twentyseventeen and noticed that my site was now displaying in two columns, which is the default setting for twentyseventeen.
It took quite a bit of searching to find a solution. Others having this problem suggested it was a plugin conflict. It was not. Others had css fixes. I solved the problem by using PHPAdmin to copy the theme options from the twentyseventeen theme modification record to my child them modification record.
I discovered there is a simple work around to set the page layout to one column when setting the front page to display the latests posts. First switch to a static front page. The Theme Options show up. Set the page layout to one page. Switch back to having the front page show your latest posts. Publish the child theme and the site will show as a single column even though it does not have a static front page.
It would be helpful if the one column/two column layout option was on the “Homepage Settings” instead of in the “Theme Options” page which is not available if you have the home page set to show your latest posts.
I’m not sure why the twentyseventeen theme designers would think that a single column layout isn’t appropriate for a site where the latest posts are the front page. When a two column layout is selected, there is so much wasted space on the left side of a page. Even a site where the front page shows the latest posts looks much better with a single column layout.
