Since you're creating this piece of content anyways, there's not any more time being spent.
You'll just bind only after you created the static content version.
I find it to be super powerful and saves so much time. It drove me insane to go unbid everything just to be able to copy-paste (will happen more than once on same element too) and if you have a library of elements (aka styleguide), which I highly recommend, all your dynamic element can be reused throughout your site. Worse case scenario, won't hurt to have an symbol being used once. Afaik, there's no limit on the # of symbols any one project can have.
I probably wasn't clear in the second half. What I meant is that the copy/paste of dynamic element should be enabled, but upon "pasting" the element in a new dynamic page, instead of webflow throwing a "Dynamic elements can't be used in a different dynamic template" (or smth to that effect), webflow could allow copy/pasting the element into the new dynamic page and keep whatever bindings are still valid while reverting the binding that are not to static content.
Does that make sense?
This is especially relevant when you need the same type of dynamic elements (like say an "article preview" dynamic collection) from pages to pages, but of course the collection content will be different.
