Use what you enjoy. It’s a shame that someone needed to fork the project to support something that would be so beneficial.

But this line ‘No warranties or guarantees of security or updates or even stability!’ personally would keep myself from using it.

Browsers play a critical role in the security of your device and I wouldn’t feel comfortable letting a hobby project assume that role.

That being said, it’s a common occurrence for forks to lag behind in security updates and ultimately your prerogative to accept that risk.
