Now we need to figure out why, as neither Tbird nor WLM 2012 do that for me, but Outlook 2016 does. And now that I've checked the settings on the two Gmail accounts I was using, this appears to be a function of Gmail Settings, Forwarding and POP/IMAP. Under those settings, IMAP section, there are two entries:
When I mark a message in IMAP as deleted:
with the options auto-expunge on (and when I have this turned on messages are not archived and the options in the next section are stippled and inaccessible)
The entry that follows is, When a message is marked as deleted and expunged from the last visible IMAP folder:, with three options which, if available a single one is selected via a radio button:
So when I have auto-expunge on, it's behaving as though auto-expunge is off but with the "Move message to trash" radio button selected. When trashed the message is not retained in the archive and is permanently expunged from the server after 30 days.
One could also, clearly, have auto-expunge off but direct Google to immediately delete the message, which bypasses the trash folder entirely.
There has got to be some client-side setting that indicates to Gmail whether a delete is actually a delete, in which case the message gets moved to Trash under the Gmail folder hierarchy, or archive, in which case the Inbox label is removed but the message still exists in All Mail.
I have found the setting in Gmail's own app, and articles regarding same, easily. Tracking it down for the other e-mail clients is not so easy.
