More like historical, this has been the case since the inital commit of zfsboot
https://github.com/freebsd/freebsd-src/blob/cd88b8869f9b2c280b1de02608f52fdf497b4cb1/usr.sbin/bsdinstall/scripts/zfsboot

Yes and back then only parts were compressed, now everything is compressed and the comments haven't been touched eversince.

This is good with me since compression is stated as a default earlier in the page, but like @diizzy said, a more specific commit message for our readers would be expedient, like:

bsdinstall/zfsboot examples: zap compress comments

Remove compression comments from examples as zroot datasets are compressed by default since FreeBSD 1?.? [0].

[0] {$COMMITID}

add ref to default compression
