How much more data do you have to send? Is it small enough you aren't concerned about impacting user traffic quotas?

Just enough to trigger the buffer... 1024-8192 bytes or something like that... a fart in space since it's just once per session!

Reminds me of needing to do similar things to convince browsers to render e.g. a custom 404 response.

Mildly annoying, but hardly onerous.
