Of course. The fixes weren't unique to systemd. Upstart addressed those issues too. The problem, either branding or adoption, is that after literally decades it hadn't been widely adopted on sysv-style systems. `/etc/rc.d/init.d/functions` was never ubiquitous enough that you could trust it existed. I've downloaded software that required it on platforms that didn't offer it and meant troubleshooting and rewriting when I should have been on to the next thing.

Maybe because they /could/ be run directly if/when service existed without warning or penalty, it also wasn't widely used.

In practice, I hit it many many times in sysv-style systems. I've used systemd systems for much less time but haven't hit a similar issue since transitioning.
