Not in my experience, but again that was quite some time ago - I think it was Android 6 the last time I did it.
ETA: although now that I think about it, it was technically done in an “unsafe” manner by exploiting vulnerabilities. For the more safety-concerned, maybe a wipe was preferred.
Typically unlocking the bootloader requires a full wipe. It’s a security method intended to keep an attacker from compromising your OS to access your data if the phone is stolen.
I’ve never rooted a phone without requiring a wipe, but I’ve owned mostly Samsung

I’ve owned pixels and Nexus and you could unlock without wipe. Locking required a wipe. Now both do not sure when it changed though.
