Feedback: HTML blocks should be optional/customizable

I understand and appreciate the purpose of the HTML blocks, but the implementation of them should be optional and/or customizable.

Use Case:

We provide article outlines that non-tech-savvy authors can easily copy and paste into new, blank articles. These outlines come pre-structured with all the necessary formatting—headings, tables, tabs, placeholders, etc.—allowing the authors to focus solely on adding content.

We do NOT want these headings, tables, tabs, placeholders, etc. to be within HTML blocks. The use of WYSIWYG is absolutely critical here.
