This sounds reasonable. At least then you could decide which balance of
risk/convenience fits their use-case for given service.

It's probably machine sent in seconds or minute after request, so doing
short-lived BGP hijack of MX might be reasonably easy way to get the email.

I have tens of coworkers who could read my SMS.

As long as user has the power to choose which risks are worth carrying, I
think it's fine.
For my examples, I wouldn't care about email/SMS risk if it's
linkedin/twitter/facebook account. But if it's my domain hoster, I probably
wouldn't want to carry either risk, as the whole deck of cards collapses if
you control my domains (all email recoveries compromised)
