Don't use it right now.  The only reason to use <iframe>s and @srcdoc
is to gain the benefits of @sandbox, and you can't depend on @sandbox
yet.  This won't be usable for a few years, until all the browsers you
care about implement @sandbox.

Then, once that happens, you can do the @src/@srcdoc trick.  Browsers
that implement @srcdoc will give the sandbox benefits without extra
network requests, and ones that don't yet will give the sandbox
benefits at the cost of extra network requests.

Right now, though, there are zero benefits to trying to use it and
plenty of penalties, as you noted.  That's fine.  It's just a young
feature that needs implementations.
