Describe the solution you'd like

I hate to chain a sequence of transforms that all

• read HTML, “load” is as a DOM, change some values, export to new HTML, then
• read HTML, “load” is as a DOM, change some values, export to new HTML, then
• read HTML, “load” is as a DOM, change some values, export to new HTML, then

Would it be possible to have a nicer experience by integrating the “read HTML, load is as a DOM” and “export to new HTML” steps inside 11ty, so that we only have to deal with the DOM?

It could use linkeDOM, which is much faster than Cheerio or other.
