What is your suggestion?

When you go to https://dev.coder.com/ without being logged in you get redirected to https://dev.coder.com/login?redirect=%2F

The %2F decodes to / meaning redirect to the base URI. That's unnecessary and (trivially) clutters the URL. We should omit it when it's meaningless.

Why do you want this feature?

Trivial aesthetic reasons

Are there any workarounds to get this functionality today?

n/a

Are you interested in submitting a PR for this?

nope
