Sure. But it's a depreciation and there's numerous similar settings that are only available by tweaking settings manually or using gnome-tweaks. Right now nearly every linux app supports select with the left button and paste with the middle. It's fast, useful, doesn't require a keyboard, etc. Amusingly I've seen various logins block control-v, but middle click works. God forbid you use a password safe with your bank login.

When you use gnome-tweaks there's a ton of "WARNING you may break things" and of course anything off the default path is likely to receive zero testing.

Personally I find middle click to paste one of the differentiators between MacOS, Windows, and Linux. I'm pretty surprised it's not more common. I was amused the iterm2 added select without having to type control-c.
