Thank you for the ping. I actually looked at this earlier today but wanted to think about it for a bit before I responded.

First, my major concern is that it has not been discussed what exactly should happen for example when a paragraph is transformed into a title block. I do feel that there needs to be a decision first.
Should the paragraph text be replaced? Or should the title of the post be update with the paragraph text?
It is not clear to me what the user's need and expectation is, and I think the scope of the change should be reduced.

Is there a reason why the edit.js file is updated instead of using a transforms.js file? I believe using the separate file is preferred.

As you found out, the block library should not depend on wordpress/editor.
If it must be used, please compare the code with how this is solved in the other blocks, and include the relevant inline comments about why an exception is needed.

Thanks for pointing that out @carolinan

I will add the transform code to a separate file, that will be the best way!

I agree. The issue was originally proposed to be transformed to Heading/Paragraph, with no mention of the reverse. Changing from Headings/Paragraph should be discussed separately.
