Support for use of an email alias for Delta Chat

Google supports automatic email aliases by putting a + extra characters immediately prior to the @.

e.g. emailaddress+deltachat@gmail.com

Could this be used to effectively make a dedicated Delta Chat address?

If enabled DC would send from this address and only respond to it, (but for all messages to it).

Not sure whether this works with gmail, but it works fine with mailbox.org (see also here: Using Delta Chat with email sub-addresses – Lenz Grimmer's random thoughts).

Fastmail supports this kind of addresses too:

That is the sort of thing I’m thinking of, but integrated into the client.

It’s something that would be very desirable once the client gets serious traction. (ie people aware of the concept, so if they saw such an address they’d know what to expect when using it from regular email.)
