I'm a little worried if we can separate mail addresses by comma easily.

My understanding is that commata are allowed in mail addresses, but only
inside quotation marks, and this usage is discouraged. Is that correct?

We could simply separate addresses at the comma, but in theory, this
may break things for users with mail addresses that contain commata.

Can we just ignore this? After all, the use case of separating mail
addresses by comma seems to be very uncommon itself (you're the first
one to ask about this in all the years). They should really be given as
separate arguments.
