Mostly replying because I’m interested in following this conversation.
Although I’m sure this is a terrible bastardization of what HubSpot intended, you can still add valid HUBBL code into the “Wrapping HMTL” of a module and accomplish some of the same things.
As a quick test, I put the {{ html }} section in a {% raw %} tag so I could see the id, and tried referencing it using {% module module_id=# %} instead of {{ html }} no_wrapper=true. Unfortunatley didn’t work. On the plus side, the other kinds of modules I tried no_wrapper on did work. So, if that helps you hack your module into doing what it needs to do, neat :-]
