These are both good points, thanks for bringing them up. I won't plan to block shipping for these but I'll follow up for both.
I filed https://bugs.chromium.org/p/chromium/issues/detail?id=1344685 to track the addition of the console warning. I filed https://github.com/w3c/csswg-drafts/issues/7499 to track clarification of the printing behavior.

It seems ::highlight customization is only supported in LayoutNG for most properties (only background-color works in legacy). I'm wondering if we should add some kind of console warning message, like for Container Queries [*], so if people see some differences in some cases they can know the reason why. Another thing that I noticed is that highlight pseudos are not being printed, I guess that was on purpose for things like ::selection or ::target-text, but should we allow printing ::highlight? Should we open a spec issue about that so it's properly defined (I didn't find anything on the specs regarding printing)? I don't mean this is a blocker for shipping, but if this is not properly defined, maybe it's time to clarify things regarding printing.
