My answer would still be yes, though I can't remember the details, I
have had issues with this in several occasions, maybe five or six (all
the times I've tried this feature since I started using Gentoo, like a
decade ago). So, it's a feature that has always been broken, in all
the stable and experimental init systems that Gentoo has had since it
was born.

I hope that can give you a better overview on what I meant above.

In that case, maybe systemd or a custom init script (even something
simple in local.start) could greatly improve your boot time without
breaking it. I don't mean you shouldn't use that feature though, I
just mean that you should be vigilant if you use it. It might just
work for your particular configuration, but it might also break at any
random moment tomorrow so you'll need to keep an eye on it and remind
to turn it off if some paranormal activity is detected in your machine
or something happens to your kittens. :)
