RIP my old friend.

What is the reason for doing this?

I don't want to manually create ISOs. I like how my custom ISO can easily be grabbed from my Releases page.

I still have release-iso.yml in my repo. Can I keep it running or will it stop working eventually?

The reason for doing this is that isogenerator-old repo is depreciated by the Universal Blue team, which made it possible to build online ISOs & release them in GitHub releases.

Their reasoning for depreciation is unreliable handling of online images by the installer itself. It would often error-out & refuse to install for some users, even if they had good internet connection. It lacked proper info on why the installer failed, it lacked progress info on how much of the image is downloaded, option to retry online-install if failed etc.
I personally never had any issue with it, but I understand & agree with their decision.

I understand your reasoning & I also miss that benefit.

You can keep running the old online ISO action & it will work just fine.
The only thing that can possibly change in the far-future, which would break things, is stuff related to Secure Boot support with enrolling security key. F.e. if Universal Blue decides that they want to re-new the secure key, than enrolling the current key will not work & SecureBoot system would fail to boot.

New isogenerator allows more customization regarding this to downstream users like us, which would prevent issues like these. It also has the benefit of ISOs working with Ventoy, auto-language + region detection & no need to manually rebase to signed image afterwards.

Unfortunately, it currently doesn't support generating online ISOs & it doesn't support upload to GitHub releases due to file-size limit.
Some users have an idea of making the GitHub action where offline ISOs could automatically build & upload to Archive.org in scheduled time. But that's just an idea, which is not yet realized.

New isogenerator is based on this upstream repo, which Universal Blue can potentially use in the future instead of their forked one.
