Headless/read-only blocks cleanup

Problem

I have a use case where I use a read-only workspace to display some blocks. Before rendering the blocks, I need to clean up the workspace, as the blocks are occasionally positioned randomly and I want the preview to be clean.

Request

It would be helpful if we could clean up the blocks without needing to render a workspace (as I only want the blocks to be visible after the cleanup) or if this could be done in read-only mode. Would prefer the latter.

Alternatives considered

Create and render a temporary workspace, render the blocks, cleanup the blocks, export the blocks state, destroy the temporary workspace, create and render the read-only workspace, load the cleaned up blocks in the read-only workspace.

Additional context

If by "headless" you mean using a Workspace that is not a WorkspaceSvg, then unfortunately it's not possible to do a cleanup because cleaning up depends on knowing the size of blocks, but we can't measure the size of a block until it has been rendered.

An alternative would be to allow a WorkspaceSvg's readonly option to be toggled after injection. This would allow you to load the program, cleanup, and then make the workspace readonly. Does that approach sound reasonable to you?
