Hem it's not a GMail specific feature but a common one (sub-addressing/plus addressing, RFC 5233) that skip inbox and drop messages in the +$name/tag dir/label...
The GMail specific feature is adding dots as you want in your mail localpart so (foobar, f.oo.bar, f.o.o.b.a.r etc @gmail are the very same mailbox).
Ok, that I did not know. Thanks!

Unless the spammer knows about this too and trims any +suffixes from the addresses.

FastMail thought of this and lets you use subdomains instead. So [email protected] gets delivered to your mailbox as user+tag@domain.
Aren’t both of those things relatively standard for email in general
This can be helpful if you're interested in tracking the origins of where your received emails come from. For instance, if you sign up your address at a website and start recieving sketchy emails with a destination for myemail+thatwebsite[at]gmail, you can easily find out where the leakage occurred.
