For what it's worth you can create a new user profile in Chrome (click your profile picture in the top left then click "add"), and it'll open a new window which is completely isolated from all your regular browsing. It's a decent approach if you want to install a ton of dev extensions.

Also, I run a paid Chrome extension and have good conversion rates from the website -> downloading the free version, so I don't think a lot of users are that bothered by this anyway. People recommend Lastpass, uBlock and Grammarly all the time, which ask for wide permissions.
