Indeed. And it's not like those ciphers are completely broken to the point of being easily exploitable.
I have some old servers with older iLO that suffer from this, and I'm only using them on a local network. Similarly, I have used the "None" cipher on a local network to sync a lot of data from my old NAS which definitely did speed things up (that box didn't have AES-NI, ancient processor).
They don't have to enable it out of the box but having it in there when needed is definitely helpful.
On another point, that 'huge diverging patch' from OpenBSD PF was all about multithreading and dramatically improving performance on modern systems, it's not like it was done for the sake of it... But it should have been kept more up to date, yes.
