Export Including Attachment

Wow I’m really shocked when I go to BW help page and found out “At this time, exports do not include file attachment data”.
I remember about few weeks ago when I export my vault to (.json) format before changing my current email for BW and then put it back after confirm that no issue with new email after couple of logins.
But fortunately I was made a copy of attachments into KeePass in case something bad happen with my BW vault.

My question, is it possible to export vault including attachments in the future update ?

Also how do you manage the exported vault ? I mean like move it to the safe place, encrypt or something like that.
